Document Type and Number:
Japanese Patent JPH02150446
Kind Code:
A
Abstract:
PURPOSE:To provide the subject composition having excellent low temperature impact resistance, weather resistance, heat resistance, appearance, etc., by compounding a specific amount of a specified polyorganosiloxane-polyalkyl (meth)acrylate complex rubber graft copolymer. CONSTITUTION:(A) 95-50wt.% of a thermoplastic polyester (e.g. polyethylene terephthalate), (B) 5-50wt.% of a complex rubber graft copolymer prepared by graft-copolymerizing one kind or more of vinylic monomers to a complex rubber comprising B1: 10-90wt.% of a polyorganosiloxane rubber component having dimethylsiloxane repeating unit in the main skeleton thereof and B2: 90-10wt.% of a polyalkyl (meth) acrylate rubber having n-butyl acrylate repeating units in the main skeleton thereof in an inseparable, mutually entangled structure and having an average particle size of 0.08-0.6mum and (C) 0-60wt.% of a filler are compounded with each other to provide the subject composition.
