ABSTRACT:
Thermoplastic blends having superior capability and homogeneity comprising a poly(phenylene oxide) resin and a resin of poly(methyl ethenyl benzene) isomers in which the predominant isomer is 1-methyl-4-ethenyl benzene, are disclosed. The poly(phenylene oxide) resin can contain substituted phenylene units and the poly(methyl ethenyl benzene) resin can be a polymer of solely methyl ethenyl benzene isomers, or a random, block or graft copolymer comprising 50 weight percent or more of methyl ethenyl benzene iosmers and up to 50 weight percent of other ethylenically unsaturated monomers.
