A hyperbranched polyetherketone and a heat-resistant blend of polyvinylchloride with the same. The polyethereketone is synthesized by self-polycondensation of 3,5-bis[4-[(2,3,4,5,6-pentafluorophenyl)carbonyl]phenoxy]-4-hydroxbenzophenone or 3,5-difluoro-4-hydroxybenzophenone, and then substituting 50 to 80 mole % of fluorine atoms present in the side chains and ends of the PEK molecule by polar groups. In addition, a blend of polyvinylchloride can be manufactured using the hyperbranched polyetherketone by a melt blending technique applicable for industrial purpose at a temperature of 180 to 120° C., and thus the blend of polyvinylchloride with the polyetherekentone can be applied to high temperature end-use products such as hot water pipes.
一种超支化聚醚酮和一种耐热的聚氯乙烯混合物。这种聚醚酮是通过 3,5-双[4-[(2,3,4,5,6-五氟苯基)羰基]苯氧基]-4-羟基二苯甲酮或 3,5-二氟-4-羟基二苯甲酮的自缩聚合成的,然后用极性基团取代 PEK 分子侧链和末端存在的 50 至 80 摩尔%的氟原子。此外,还可以使用超支化聚醚醚酮,通过适用于工业用途的熔融混合技术,在 180 至 120 摄氏度的温度下制造聚氯乙烯混合物,因此聚氯乙烯与聚醚醚酮的混合物可用于高温终端产品,如热水管。
