FORMMASSE AUS POLYPHENYLENETHER UND POLYAMIDHARZ.

摘要

A moldable composition comprises; by weight of components (1) + (2);

  (1) 50-97% of a polyphenylene ether (which may be a copolymer), e.g. poly(2,6-dimethylphenol), of a mol. wt. so as to have intrinsic viscosity of 0.35-0.7 dl/g at 30 DEG C, and a polyamide resin (e.g. a nylon);
  (2) 3-50% of a block copolymer A-B @@A-B@@@@A)n where m=0 or an integer, n=0 or 1, A is an aromatic vinyl compound (e.g. styrene) and B is a conjugated diene (e.g. butadiene) and may include another hydrocarbon; block A content is 20-50%; the copolymer having a solution viscosity at 25 DEG C of 200-100,000 cps; and
  (3) 0.01-30% of a compound having in its molecule an unsaturated bond and a polar group, e.g. having affinity to the amido link in the polyamide (e.g. an unsaturated dicarboxylic acid or an hydride).

The composition is moldable and has good mechanical strength and solvent resistance.
