Abstract

A molding composition consists of by weight (A) a partially crystalline thermoplastic polyamide (99-10%); and (B) a copolymer (1-20%) of an olefin with a (meth)acrylic ester of a 1-4C alcohol, this copolymer having an MFI >=50 g / 10 minutes.

Description

technical field [0001] The present invention relates to molding compositions based on at least one semi-crystalline thermoplastic polyamide and at least one copolymer, wherein the copolymer consists of at least one olefin, preferably an alpha-olefin, and at least one Atomic aliphatic alcohol methacrylate or acrylate composition, the MFI (melt flow index) of the copolymer is not less than 50g / 10min, also relates to the preparation method of such molding composition, and the use of such molding composition Applications for the production of molded parts or semi-finished products by injection molding or extrusion. Background technique [0002] High flow thermoplastic compositions are of interest in various fields of injection molding. For example, thin-walled parts in the electrical, electronics and automotive industries require thermoplastic compositions with low viscosity to allow the material to be injected into the mold of a suitable injection molding machine with minimal ...
