发明名称 Polyphenylene co-polymers
摘要 A new class of polyarylene co-polymers include repeating units comprising one or more arylene units having the general formula (-Ar-/-Y-)n, where Y is a divalent group chosen from nil, -Z-, -Z-Ph-, and -Ph-Z-Ph-, where Z is a divalent group chosen from the group consisting of -O-, -S-, -NR-, -O(CO)-, -O(CO2)-,-(CO)NH(CO)-, -NR(CO)-, phthalimide, pyromellitimide, -CO-, -SO-, -SO2-, -P(O)R-, -CH2-, -CF2-, and -CRR'-; Ph is phenylene (ortho, meta or para); and n is greater than 4. The co-polymers are useful as molding resins, and composite matrix resins, and where Ar is heteroarylene as ion exchange resins.
