摘要:
Thermoplastic polyester molding compositions with improved heat distortion point contain, per 100 parts of a linear saturated polyester, from 1 to 100 parts of a rubbery graft copolymer, from 10 to 100 parts of an .alpha.-methylstyrene/acrylonitrile copolymer, and from 0 up to 80, preferably 10 to 80 parts of a filler, especially glass fibers as the filler. They can be converted to shaped articles by extrusion or injection molding.
摘要:
A flameproofed nylon molding composition which can be processed by thermoplastic methods and which contains, as the flameproofing agent, from 5 to 30% by weight of brominated styrene oligomers and a synergistic metal oxide. The compositions may be used for the manufacture of injection moldings for the electrical industry.
摘要:
Stabilized polyester molding compositions in which the stabilizer is a carbodiimide of the formula ##STR1## where R is hydrogen, alkyl, halogen or nitro, at least one of the substituents R in the ortho-position to the carbodiimide group must differ from hydrogen, and the carbodiimide molecule contains, as substituents R, 2 alkyl groups and 2 nitro groups, or from 4 to 6 chlorine atoms, or 2 alkyl groups and from 4 to 6 chlorine atoms, or 2 chlorine atoms and 2 nitro groups, or 4 chlorine atoms and 2 bromine atoms.
