A polyphenylene ether composition comprising: 100 parts by weight of (A) a polyphenylene ether resin or a combination of a polyphenylene ether resin and a styrene resin; 1 to 40 parts by weight of (B) a flame retardant which is comprised mainly of at least one member selected from the group consisting of two specific condensed phosphoric esters; 0.3 to 10 parts by weight of (C) a hydrogenated block copolymer which is defined as a hydrogenation product of a block copolymer comprising a polymerized styrene block and a polymerized conjugated diene block, wherein at least one polymerized styrene block has a number average molecular weight of 15,000 or more; and 0.3 to 10 parts by weight of (D) a polyolefin resin, wherein the weight ratio of the component (C) to the component (D) is from 70/30 to 15/85.

Polyphenylene ether composition

The present invention relates to a polyamide composition comprising (A) polyamide, (B) polyphenylene ether, and (C) an ethylene-&#x3b1;-olefin copolymer prepared using a single site catalyst. The resin composition of the present invention can provide a polyamide composition having excellent impact resistance and excellent surface smoothness, and displaying only small dimensional changes after water absorption.

Polyamide composition

A flame-resistant polyamide resin composition comprising components:

Flame-resistant polyamide resin compositions and flame retardants

Olefin polymer and a resin composition containing the same

A high impact polyamide composition comprising at least one polyamide, at least one ethylene ionomer resin and at least one oxide or carbonate compound is specific weight proportions, wherein the polyamide has a relative viscosity of at least 3.15 in 98% sulfuric acid. The composition may further comprise an elastomeric olefin copolymer, an elastomeric styrene copolymer and/or a polyvalent alcohol. The polyamide composition has excellent mechanical strength, thermal resistance and impact strength even at weld-line portions so that it can advantageously be employed for manufacturing various shaped articles, such as automobile parts and sporting goods.
