Barrier Properties Ticona Topas COCs provide excellent moisture control. They have roughly double the moisture barrier of HDPE, triple that of LDPE, and seven times that of unoriented polypropylene (PP). They also provide high clarity and stiffness. Grades are available with the heat resistance to withstand hot-fill and microwave processes. ... 

Downgauging As the amount of Ticona Topas COC in a PE blend increases, film stiffness increases. This allows film thickness to be reduced while holding stiffness constant. ...

In our laboratory, polymer CE microchips in combination with EC detection have been successfully used as miniaturised devices for determination of clinically important analytes. As commented in Section 34.1.2, poly(methylmethacrylate) (PMMA) is one of the most used polymers for manufacturing microchips. Recently, cyclic olefin copolymers (COCs) such as Topas (thermoplastic olefin polymer of amorphous... 

Within the past five years, commercial interest in metallocene catalyst components for the polymerization of olefins has increased enormously. Commercial production of a rising number of polyolefin types from different companies is creating a burgeoning and highly diversified demand for metallocenes. New brand names (e. g., Metocene (Basell), Elite (Dow Chemical), Engage (DuPont), Exact (ExxonMobil), Luflexen (Basell), Apel (Mitsui Chemicals), Borecene (Borealis), Finathene (TotalFinaElf), Topas (Ticona), just to name a few) characterize polyolefins such as PE, elastomers, PP, cycloolefin copolymers (COCs) and PS from metallocene-type catalysts [1-3]. 

Within the family of cycloolefin co-polymers, the most important from a material properties standpoint, are the ethylene/norbornene co-polymers. These co-polymers, dubbed COC for cycloolefin co-polymers, are produced by Ticona and Mitsui under the tradenames Topas and Apel , respectively. An overview of properties and applications (for example, blisters for pills) can be found on Ticona s Topas homepage.607 Detailed ethylene/norbornene copolymerization studies with different 4/-symmetric and ansa-Cp-amido catalysts, with listing of co-polymerization parameters, have been published.608 611 NB is inserted exclusively in the cis-2,3-exo-modc (Scheme 25), and most of the metallocene catalysts tend to produce alternating co-polymers,609 612 due to the low reactivity of the M-NB intermediate toward further NB insertion. This mode of NB insertion prevents f3-H transfer, and thus ethylene/ norbornene co-polymers have increasing molecular masses at increasing NB content.611...

Cyclic olefin copolymers (COC) are copolymers of ethylene and norbornene (2,2,1 bicycloheptane), made using metallocene catalysts. They are amorphous polymers with excellent clarity, low density, high strength, and stiffness. Currently the major manufacturer is Ticona, which sells them under the trade name Topas. 

General Description Ticona Topas are amorphous, glass-clear copolymers of ethylene and norbomene. Ticona Topas cyclic olefin copolymers (COC) form strikingly clear films. When blended with polyethylene (PE), they enhance the stiffness and heat-seal behavior of blown and cast films and offer high moisture barrier, clarity, and stiflfiiess. The Tieona Topas product line features several grades differentiated by heat deflection temperatures ranging from 80° to 18o°c.[ioi5]...

The first group consists of amorphous thermoplastic engineering polymers. These are cyclic olefin polymers (COP) or cyclic olefin copolymers (COC) with ethylene. They were commercialized, for example, as Zeonex (in 1991) and Zeonar (by Zeon), as Topas (Polyplastics), Apel (Mitsui), and Alton (JSR). Topas was originally part of Ticona, before it was sold to Daicel in 2005. A Topas plant with a capacity of 30,000 tpa started up in Oberhausen, Germany, in September 2000. Until that time, world capacity from 4 pilot-scale plants was around 10,000 tpa.

Copolymers made from a-olefins and cyclic olefins have been known for nearly 50 years (1,2). Ethylene-norbomene (Et-Nb) copoljrmers are specifically described in the patent bterature as long ago as 1973 (3), with further patent filings since then (4-6). The general class of thermoplastic cyclic olefin copolymers (COCs) includes products from Mitsui Chemicals (7), Japan Synthetic Rubber (8), Nippon Zeon (9), and Ticona (10). Some of these products are manufactured by ring-opening metathesis and others by addition polymerization. Only the COCs made by Ticona, a division of Celanese AG, under the trademark Topas, are Et Nb copolymers. These products, for which Ticona started up a 30,000-t plant in September 2000 (11), are described in this article. 

In December 2005 Celanese contracted to sell its loss-making Topas, cyclo-olefin copolymers (COC) operation to a Daicel (55%)/Polyplastics (45%) joint venture. This COC business has approximately 100 employees at production and research facilities in Oberhausen and Frankfurt as well as in the UK. Following the sale, which involves the transfer of all production faciUties and employees to the new joint venture, the headquarters of the business will remain in Germany. Ironically, Mitsui Chemicals announced plans to increase COC production by 600 tonnes per year, citing forecast rising demand of 20% per year for its own Apel COC product. Earlier, Ticona had announced its intention to withdraw from its Pemeas joint venture which had lost US 12 million in 2003. 

Ethylene/norbornene copolymers are presently available commercially from TOPAS Advanced Polymers, Inc., a company formed in 2006 after early development efforts by Hoechst AG and Mitsui Petrochemical. Hoechst initiated the commercialization of this cyclic olefin copolymer (COC) in 1990, and Mitsui Petrochemical became involved in evaluating the manufacture of these copolymers in a continuous pilot-scale operation in 1993. TOPAS Advanced Polymers, Inc., is a joint venture of Daicel Chemical Industries Ltd., and Polyplastics Co., Ltd., with headquarters in Frankfurt, Germany, and a United States subsidiary in Florence, Kentucky. The structure of this copolymer is shown in Figure 4.26.

Ticona s COC (cyclic olefin copolymer) (Topas ) has been noted to significantly reduce the part warpage of fiberglass filled polypropylene. Commercial utility in automotive apphcations has been noted. 

By copolymetization of cydic olefins, especially noibomene with ethene or propene, a cydoolefin copolymer (COC) can be produced. Hiese new materials have been the focus of academic and industrial research. Ethene-norbornene copolymers (Topas ) are usually amorphous and show excellent transparency and high refractive index, making them suitable for optical applications. Zeonex is an amorphous cydoolefin polymer (COP) with a cydic structure in the main chain polymerized by ROMP of norbornene derivatives, followed by hydrogenation of double bonds, with properties similar to Topas. " Detailed information can be found in spedal reviews and books. " ... 

Cyclic olefin copolymers (COC) are an amorphous glass clear copolymer of ethylene and norbomene, made via proprietary metallocene catalysts. The material was developed by Ticona GmbH and is now being marketed under the Topas trade name. 

COC is a relatively new commercial polymer. Four commercial sources are available under the TOPAS , ApeF, Zeonor and Zeonex , and Arton product names, supplied by Topas Advanced Polymers, Mitsui Chemicals, Zeon Chemical and Japan Synthrtic Rubber. COC is a random copolymer of ethylene and norbomene. Norbomene is synthesized via Diels-Alder reaction of ethylene and cylopentadiene. Polymerization of ethylene and norbomene using metallocene catalysts produces cyclic olefin copolymer. Large bulky cyclic rings randomly distributed in a polyethylene backbone prevent crystallization of the ethylene, creating an amorphous morphology.
