Thermoplastic resin composition
First Claim
1. A thermoplastic resin composition, comprising:
- (a) a polyphenylene ether resin or a resin composition containing a polyphenylene ether,(b) (i) a modified propylene polymer obtained by grafting a propylene polymer with a styrene-based monomer or a mixture of a styrene-based monomer and a monomer copolymerizable with the styrene-based monomer or (ii) a composition containing said modified propylene polymer and a propylene polymer, and(c) a rubbery substance, wherein the component (b) is in a state of matrix phase, and the components (a) and (c) each is in a state of dispersion phase.

Abstract
Disclosed are thermoplastic resin compositions comprising:
(a) a polyphenylene ether resin or a resin composition containing a polyphenylene ether,
(b) (i) a modified propylene polymer obtainable by grafting a propylene polymer with a styrene-based monomer or a mixture of a styrene-based monomer and a monomer copolymerizable with the styrene-based monomer or (ii) a composition comtaining said modified propylene polymer and a propylene polymer, and
(c) a rubbery substance,
wherein the number mean particle size of the component (a) and (c) in the dispersion phase being from 0.01 to 20 μm, the proportion of the component (a) to the sum of the components (a) and (b) being 1 to 80% by weight, that of the component (b) to the sum of the components (a) and (b) being 99 to 20% by weight, and the proportion of the component (c) to the sum of the components (a) and (b) being 1 to 50 parts by weight per 100 parts by weight of (a) plus (b). The thermoplastic resin composition has good moldability and yields molded articles having well-balanced physical properties.
