Aliphatic polyketones are made from the reaction of olefin monomers and carbon monoxide using a variety of catalysts. Shell commercialized a terpolymer of carbon monoxide, ethylene, and a small amount of propylene in 1996 under the trade name Carilon (structure 4.79). They have a useful range between the Tg (15°C) and (200°C) that corresponds to the general useful range of temperatures for most industrial applications. The presence of polar groups causes the materials to be tough, with the starting materials readily available. 

Polyketone (PK) ( CARILON ) is a new polymer with an attractive combination of properties (very tough, high abrasion resistance, high temperature resistance, easy to process, good chemical resistance and barrier properties). It is trying to find its way in various potential applications. 

Strictly speaking, condensation polymers such as polyesters could be considered to belong to this category. Also polyketone ( Carilon ) would be a strictly alternating copolymer, if the regularity would not have been disturbed by a third comonomer, propylene.

CO to give the engineering thermoplastic polyketone, Carilon [45, 46]. Indeed, when a well-defined complex was used (Fig. 7.12), exceptionally high activities were observed [46], with turnover frequencies (TOFs) higher than the conventional catalyst in methanol as solvent. 

The new family of thermoplastic, perfectly alternating olefin/carbon monoxide polymers provides a superior balance of performance properties not found in other commercial materials. The first commercial polymer will be an ethyl-ene/propene/CO terpolymer which will be marketed by Shell under the trade-name Carilon . 

A new generation of polymers, e. g., Shell s Carilon, was developed from the discovery of the perfect CO/olefin alternating principle within the short time span of less than ten years. Systematic mechanistic work in this area has yielded a highly efficient carbonylation of propene (TON = 4 X 10 ) in the presence of palladium(II) catalysts to methyl methacrylate (cf. Section 1.3.2.3) [66 e].

The copolymerization of alkenes with carbon monoxide has attracted the attention of chemists for many years [1]. Following the commerciahzation of Carilon, an alternating olefin carbon monoxide terpolymer based on ethene and small amounts (5-10%) of propene (Scheme 8.1, 1), by Shell [2, 3] in the 1990s interest in the identification of new and more active catalysts and of the stereochemical characteristics of the reaction has grown. 

Even after Shell announced the closure of their plant for Carilon production and despite the uncertain future of this commercial thermoplastic material, investigations are still being conducted. This is probably a consequence of the growing interest in catalysis by late transition metals for the polymerization and co-poly-merization of olefins. Comprehensive reviews of this subject have appeared [4, 5] and will be taken as the basis for the following discussion. 

Aliphatic polyketone based on carbon monoxide, ethylene and a small amount of propylene, commercialised by Shell under the trademark CARILON Polymer (PK-EP), see Chapter 9. 

A unique catalyst invention at the Shell Research Laboratories in Amsterdam in 1982 [l, 2, 3] made it possible to polymerise carbon monoxide and alpha-olefins such as ethylene into linear, perfectly alternating structures. This led directly to the development of a new class of thermoplastic polymers known as aliphatic polyketones (PK), which Shell is commercialising under the trademark CARILON. 

The most recent addition to the engineering polymer field is the ethylene/carbon monoxide (COPO) alternating copolymers initially introduced by Shell. The commercial polymer is highly crystalline and believed to contain small amounts of propylene to reduce the crystalline melting point to allow a broad window of process-ability. COPO should offer serious competition to polyacetal, PA, and PBT. With the favorable raw materials cost, COPO should be a successful and competitive entry. As is now expected with new polymers, intense blend patent activity accompanies the introduction. This has also occurred with COPO as is noted in various U.S. patents involving COPO blends (See Table 17.4). COPO polymers are available from Shell (Carilon ) and BP (Ketonex ). 

The copolymerization of ethylene and carbon monoxide to give alternating copolymers has attracted considerable interest in both academia and industry over recent decades [1, 2]. Attention was focused on aliphatic polyketones such as poly(3-oxotrimethylene) (1) because of the low cost and plentiful availability of the simple monomers. The new family of thermoplastic, perfectly alternating olefin/ carbon monoxide polymers commercialized by Shell provides a superior balance of performance properties not found in other commercial materials the an ethylene/ propene/CO terpolymer is marketed by Shell imder the tradename Carilon .

Carbonylation of some alkenes catalyzed by a cationic Pd complex yields polyketones, which are alternating copolymers.

Ethylene-Carbon Monoxide Copolymers (ECOs). These polymers are random copolymers of ethylene and carbon monoxide, with properties similar to low-density polyethylene. They are sold by Shell under the trade name Carilon. These polymers exhibit low water absorption and good barrier properties, but they are susceptible to UV degradation. They find application in packaging, fuel tanks, fuel hnes, and in blends.
