THERMOPLASTIC COMPOSITION Russian patent published in 1999 - IPC

FIELD: machine building, more particularly automobile industry. SUBSTANCE: present invention describes thermoplastic composition which comprises linear aliphatic polyamide, alpha α- olefin, polymer, inorganic dispersive filler and modifier. Modifier includes combination of finely split mica with characteristic ratio of at least 30, surface of which is coated with polyvalent metal oxide, and powder- like filler with particle size of at least 90 mcm. Modifier is chemically active compound with at least two homogeneous functional groups from among epoxy, maleimide or isocyanate groups, ratio of composition components being as follows (wt %): alpha α- olefin polymer, 1.0-30.0; finely split mica with characteristic ratio of at least 30, 2.0-20.0; powder-like filler with particle size of less than 90 mcm, 0.5-20.0; modifier, 0.2-4.0; linear aliphatic polyamide, the balance. EFFECT: improved impact viscosity and lower water absorption. 5 cl, 18 ex, 2 tbl
