Description

technical field

[0001] The present invention relates to a kind of composition of nylon, rubber and styrenic terpolymer, especially about containing nylon 6 (PA6), acrylonitrile-butadiene-styrene copolymer (ABS) and styrene-propylene A polymer composition obtained by blending nitrile-maleic anhydride (maleic anhydride) copolymer (SAM). Background technique

[0002] Nylon (PA) has become a popular engineering resin because of its excellent strength, hardness, low coefficient of friction, wide service temperature, chemical resistance and wear resistance. However, such resins have inherent high notch sensitivity, ie exhibit a ductile side when not notched and brittle fracture when notched; and brittle fracture characteristics at low temperature and severe loading conditions. However, the chemical functional groups (amino group and carboxyl group) contained in the end of PA molecules bring convenience to its modification.

[0003] PA / ABS alloy is a...
