A novel resin composition improved in moldability and impact resistance, comprising (A) a polyphenylene oxide having a molecular weight of 5,000 or higher, (B) an aromatic hydrocarbon-formaldehyde resin or a modified aromatic hydrocarbon-formaldehyde resin, and, if necessary, (C) a rubbery polymer, the weight ratio of the resin (A) to the resin (B) being from 10:90 to 99:1 and the amount of the rubbery polymer (C) being 3 to 40 parts by weight per 100 parts by weight of the sum of the resins (A) and (B). This resin composition has excellent mechanical and electrical properties of the polyphenylene oxide together with an improved moldability, impact resistance, and adhesiveness.
A resin composition containing a polyphenylene oxide, comprising (A) a polyphenylene oxide having the following formula and having a molecular weight of 10,000 or higher:
A resin composition containing polyphenylene oxide, comprising (A) one member selected from the group consisting of (i) poly(2,6-dimethyl-1,4-phenylene)oxide and (ii) a copolymer composed of 5 mole % of 2,3,6-trimethylphenol and 95 mole % of 2,6-dimethylphenol, (B) a p-tert-butyl-phenolmodified mesitylene-formaldehyde resin and, (C) a styrene-butadiene-styrene block copolymer, the weight ratio of (A) to (B) being from 50:50 to 85:15 and the amount of (C) being from 5 to 25 parts by weight per 100 parts by weight of the total weight of (A) and (B).
A resin composition containing polyphenylene oxide, comprising (A) poly(2,6-dimethyl-1,4-phenylene) oxide having an intrinsic viscosity of 0.52 dl/g, (B) a p-tertbutylphenol-modified mesitylene-formaldehyde resin and (C) a styrene-butadiene-styrene block copolymer, the weight ratio of (A):
