摘要：The moulding compositions contain, in each case based on 100 parts by weightof the sum of A, B and, if used, C, A) from 10 to 90 parts by weight of polyphenyleneether, B) from 10 to 90 parts by weight of an impact-modified styrene polymercomprising b1 from 60 to 80% by weight of a hard matrix built up from a styrene
polymer, and b2 from 20 to 40% by weight of a soft phase which - is distributed uniformlyin the hard matrix, - is obtainable by polymerisation of the monomers of the hard matrixin the presence of a linear styrene-butadiene two-block copolymer comprising from 36to 45% by weight of styrene and from 55 to 64% by weight of butadiene, - has a meanparticle diameter d50 (volume average) in the range from 0.25 to 0.38 mu m, a particlesize distribution width d95-d5 in the range from 0.2 to 0.6 mu m, a d60 value in the rangefrom 0.26 to 0.4 mu m and a d90 value in the range from 0.4 to 0.75 mu m, and C) from 0to 50 parts by weight of a reinforcing agent, and are used to produce mouldings.
