摘要:
Disclosed is an article for the optical storage of data having low birefringence prepared from a mixture of a polycarbonate and a cycloaliphatic polyester. The article may optionally have stabilization and mold release additives that retain transparency, color and processability.
摘要:
Reinforced, molding compositions having improved ductility and melt flow properties. The present compositions contain a cyclo aliphatic polyester resin preferably comprising the reaction product of a cycloaliphatic C.sub.6 -C.sub.12 diol or chemical equivalent and C.sub.6 -C.sub.12 cycloaliphatic diacid or chemical equivalent, preferably an impact modifying amorphous resin which increases the ductility of the polyester resin but reduces the melt flow properties thereof, a high molecular weight polyetherester polymer which increases the melt flow properties of the polyester polymer without reducing the ductility thereof, and a glass filler to reinforce and stiffen the composition and form a reinforced molding composition.
摘要:
Multilayer plastic composite articles comprising a thermoplastic resin substrate which can be a polycarbonate, an ABS or ASA resin, a polyphenylene ether or polyphenylene ether/polystyrene blend , an polyester or an admixture of polycarbonate with ABS, ASA or polyester and at least one surface layer comprising a cyloaliphatic polyester or cycloaliphatic polyester blend which is adherent to at least one surface of the substrate. Decorative layers can be located between the substrate and the surface layers.
