Abstract
Disclosed herein is a thermoplastic resin composition which comprises:
(a) polyphenylene ether or a composition containing polyphenylene ether,
(b) (i) a modified propylene polymer grafted 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,
(c) a rubbery substance, and at least one component selected from the following three components;
(d) a styrene resin having a melt index of 8 or above (at 250° C. under a load of 5 kg),
(e) a low-molecular weight hydrocarbon resin, and
(f) white oil and/or liquid paraffin.
This thermoplastic resin composition exhibits not only good moldability but also well-balanced physical properties and heat resistance, and can be easily processed into molded articles having outstanding physical properties.
