RESIN COMPOSITION FOR MOLDING MATERIAL

摘要

PURPOSE:To obtain a resin composition excellent in dimensional accuracy, dimensional stability, moldability and physical properties by adding a specified inorganic filler to a mixture of a specified polyamide mixture with a (co)polymer of a vinyl monomer. CONSTITUTION:The title resin composition is prepared by adding 30-250 pts.wt. inorganic filler (B) comprising 20-85 pts.wt. glass filler (a) comprising 5-90 pts.wt. glass fiber comprising both chopped strand and milled fiber and 95-10 pts.wt. glass beads and 80-15 pts.wt. calcium carbonate (b) to 100 pts.wt. resin composition (A) comprising 60-100 pts.wt. polyamide resin mixture comprising 50-99 pts.wt. polyamide resin obtained from xylylenediamine and a linear aliphatic alpha,omega-dibasic acid and 50-1 pt.wt. polyamide 66 and 40-0 pt.wt. polymer or copolymer obtained by polymerizing a vinyl monomer.
