METHOD OF MANUFACTURING A GRAFT COPOLYMER COMPRISING POLYPHENYLENE ETHER

摘要

INVENTION: A METHOD OF MANUFACTURING A GRAFT COPOLYMER COMPRISING POLYPHENYLENE ETHER A method is provided in which copolymer of polyphenylene oxide with styrene and/or other vinylic monomer are readily prepared in high yields of graft efficiency by radical polymerisation of vaporised monomer onto solid polyphenylene oxide and thus resultant polymer has improved characteristics e,g. in fracture strength and chemical resistance.
