Polyamide moulding compositions with improved flowability

Abstract

The present invention relates to a thermoplastic polyester and olefin-alkyl (meth)acrylate copolymer with high melt flow index, in which the thermoplastic polyeste contains a alpha-alkene and at least one of (meth)acrylate(s) with 1-4C aliphatic alcohols showing a melt flow index(MFI) of not less than 50 g / 10 min. The present invention also relates to a method of preparing the thermoplastic polyester and to the use of the thermoplastic moulding material in electric, electrical, telecom, motor or computer industries, and model piece application in gym, domestic appliance, medicine or entertainment industries.

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 ...
