Polyblends of polyphenylene oxide and styrene-acrylonitrile polymers having broad acrylonitrile compositional distribution

摘要

Polyblends comprising about 10 to about 90% by weight of polyphenylene oxide and about 90 to about 10% of SAN or ABS polymer comprising 8 to 17 average % by weight acrylonitrile in which the acrylonitrile compositional distribution in the SAN or ABS polymer is broad in that the standard deviation of the weight % AN about the mean value is at least about 3.5%.
