Poly(phenylene ether). The only commercially available thermoplastic poly(phenylene oxide) PPO is the polyether poly(2,6-dimethylphenol-l,4-phenylene ether) [24938-67-8]. PPO is prepared by the oxidative coupling of 2,6-dimethylphenol with a copper amine catalyst (25). Usually PPO is blended with other polymers such as polystyrene (see PoLYETPiERS, Aromatic). However, thermoplastic composites containing randomly oriented glass fibers are available.

Mitsui Chemicals is launching a new grade of carbon nanotube reinforced thermoplastic poly-imide, Aurum CNT, with supplementary specific properties such as dust reduction and antistatic behaviour. Targeted applications are, for example, processing jigs for semiconductor or hard disk manufacturing, and parts for hard disk drives.

PIB based thermoplastic poly(urethane)s (TPU)s have been synthesized. These composites exhibit enhanced mechanical properties. Poly(tetramethylene oxide) (PTMO) has been used as a compatibi-lizer. 

The use of a protective polymer film as barrier has been proposed. This barrier consists essentially of a thermoplastic poly(ester) resin, which is a homopolymer or copolymer adduct of an aromatic dicarb-oxylic acid in an active hydrogen-containing material. However, this poly(ester) resin copolymer has a poor compatibility with styrene resins. Thus, the protective polymer film lacks the desired regrind capability.

Carbodiimides are also used as catalysts in the formation of polyamides from dicarboxylic acids and diisocyanates. The carbodiimide catalyst is generated in situ from the diisocyanate using dimethylphospholene oxide as the catalyst. In this manner segmented thermoplastic poly(ether amides) and poly(ester amides) are obtained from the acid terminated monomers and diisocyanates by reaction polymerization processes. This reaction is best conducted in a vented extruder because carbon dioxide is the byproduct.

We report the first syntheses of the selenium and tellurium analogs of the thermoplastic poly-p-phenylene sulfide (PPS), i.e., PPSe and PPTe, by reaction of p-dihalobenzenes with new alkali chalcogenide reagents under conditions significantly milder than those reported for PPS. The chemical, thermal, structural, and electrical properties of PPSe and PPTe are compared to those of PPS. While PPSe exhibits good thermal stability,...

Thermoplastic poly(lactic acid) (PLA) is obtained by polycondensation of the acid or by ring-opening of the lactide. Its mechanical performance is similar to that of PS. Lactic acid (LA) can be produced by fermentation of coal, petroleum or namral gas. PLA is sensitive to enzymatic and chemical hydrolysis. It has been used for medical implants, dmg delivery, packaging and consumer goods. LA can be copolymerized with ethylene glycol into highly hydrophilic poly(ether-ester) block copolymers. Similarly, LA was copolymerized... 

Plastisols and organosols are a special case of physically drying coatings systems in which the binders consist of finely dispersed poly( vinyl chloride) or thermoplastic poly(meth)acrylates suspended in plasticizers. Organosols also contain some solvent. On drying at elevated temperatures, the polymer particles are swollen by the plasticizer, a process known as gelation.
