Thermoplastic molding masses.

摘要

The moulding masses contain, as essential components,
A) from 5 to 94% by weight of a polyamide,
B) from 5 to 94% by weight of a polyphenylene ether,
C) from 1 to 20% by weight of a partially hydrogenated PQP' block copolymer in which
alpha ) the blocks P and P' are built up from vinylaromatic monomers, and the total amount of these blocks in the block copolymer is the range from 25 to 40% by weight,
beta ) the molecular weight (number average) of block P is not greater than 8,000 and is less than the molecular weight (number average) of block P'
gamma ) block Q is built up from conjugated diene monomers and makes up a total of from 60 to 75% by weight of the block copolymer, and
delta ) from 5 to 30% by weight of the double bonds in block Q are unhydrogenated, and
D) from 0 to 50% by weight of a vinyl aromatic polymer.
