Dow Engineering Plastics offers a wide range of different polymers including ABS, polycarbonate, liquid crystal pol5miers, polyurethane and polypropylene based polymers. Dow is the world s fourth largest ABS producer and ranks third in the polycarbonate market. Dow s ABS business is largely concentrated in Europe and the USA, whereas the company s polycarbonates are also well represented in Asia through joint ventures. [Pg.153]

Yet another recent development has been the alloying of polycarbonates with liquid crystal polymers such as Vectra (see Section 25.8.1). These alloys are notable for their very good flow properties and higher strength and rigidity than conventional bisphenol A polycarbonates. [Pg.579]

Over the years polymers have been produced suitable for use at progressively higher temperatures. Where this is a requirement, it is usual first to decide whether a rubbery or a rigid material is required. If the former, this has been dealt with by the author elsewhere." If the latter, it is usually convenient to look in turn at polycarbonates, PPO-based materials, polyphenylene sulphides, polysul-phones, polyketones such as PEEK and PEK, polyamide-imides, poly-phthalamides, fluoropolymers, liquid crystal polymers and polyimides.

Engineering plastics (qv) such as acetal resins (qv), polyamides (qv), polycarbonate (qv), polyesters (qv), and poly(phenylene sulfide), and advanced materials such as liquid crystal polymers, polysulfone, and polyetheretherketone are used in high performance applications they are processed at higher temperatures than their commodity counterparts (see Polymers containing sulfur).

Recently very interesting results have been reported on the behaviour of polymer/liquid crystal membrane consisting of bisphe-nol A polycarbonate (PC) and of N-ethoxybenzylidene A -n-butyl aniline (EBBA). This substance shows a crystal-nematic transition at 304° K and nematic-to-isotropic phase transition at 355° K. [Pg.246]

The lack of liquid crystal properties in this polymer series was not completely unexpected and inspection of molecular models allows one to observe only non-linear, highly bent conformations of the diphenyl carbonate repeating unit. Very recently, investigations by Flory and coworkers on model analogues of polycarbonates have shown that in the crystal the carbonate group is coplanar and with... [Pg.273]

The engineering polymers that have already reached maturity consist of the Nylons (PA), polycarbonate (PC), acetal (POM), polyesters (PBT and PET) and Noryl (PPO). Their relative price is aroxmd 3. Including very novel polymers, a prestigious high priced group consists of the advanced engineering polymers (high performance) polysulfone (PSU), polyphenylene-sulfide (PPS), fluoroethylenes (PTFE and its derivatives), polyamide-imide (PAI), polyether-imide (PEI), polyethersulfone (PES), polyether-ether-ketone (PEEK), aromatic polyesters and polyamides, polyarylates and liquid-crystal-polymers (LCP).

Typical plastics, including polymethylmethacrylate (PMMA), polycarbonate (PC), cyclic olefin copolymer (COC), polysulfone (PSU), polyetheretherketone (PEEK), liquid crystal polymers (LCP), polystyrene(PS), polyethylene terephthalate (PET), etc., have been used for microfluidics. COC is the most commonly used polymer, accounting for around 80 % of all applications, because of its good optical properties [2]. [Pg.2094]

In general, template method is classified by soft and hard templates. Whereas anodic aluminum oxide (AAO) membrane, track-etched polycarbonate (PC) and zeolite can be used as hard templates, soft templates include surfactant, cyclodextrin, liquid crystal, etc. Compared with soft and hard templates, template-free method represents the fabrication technique of conducting polymer nanomaterials without the template, which is discussed in this section [115]. [Pg.199]

There are two types of disparities between the steady-state and dynamic flow behavior, one related to the interlayer slip (Eq. (2.56)) and the second to the flow engendered migration of the low viscosity component to the high stress location. Blends of liquid crystal polymer (LCP) with polycarbonate (PC) or poly(ethylene-terephthalate) (PET) may serve as an example of the first type [321,322], whereas those of EPDM (ethylene-propylene-diene terpolymer) with poly(vinylidene-co-hexafluor-opropylene), Viton , exemplify the second [323-325]. In both cases the steady-state shearing was performed in a capillary viscometer- the viscosity ratio of the dynamic to the steady-state data for these two blends was about two and six, respectively.

Engineering thermoplastic resins (ETP) are those whose set of properties (mechanical, thermal, chemical) allows them to be used in engineering applications. They are more expensive than commodity thermoplastics and generally include polyamides (PA), polycarbonate (PC), linear polyesters such as polyethylene terephthalate (PET) or polybutylene terephthalate (PBT), polyphenylene ether (PPE) and polyoxymethylene (POM). Specialty resins show more specialized performance, often in terms of a continuous service temperature of 200°C or more and are significantly more expensive than engineering resins. This family include fluoropolymers, liquid crystal polymers (LCP), polyphenylene sulfide (PPS), aromatic polyamides (PARA), polysulfones (P ), polyimides and polyetherimides. [Pg.627]
