A hyperbranched polyetherketone and a heat-resistant blend of polyvinylchloride with the same. The polyetherketone is synthesized by self-polycondensation of 3,5-bis[4-[(2,3,4,5,6-pentafluorophenyl)carbonyl]phenoxy]-4-hydroxybenzophenone 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 polyetherketone can be applied to high temperature end-use products such as hot water pipes.
一种超支化聚醚酮和相同的耐热聚氯乙烯混合物。聚醚酮是通过3,5-双[4-(2,3,4,5,6-五氟苯基)羰基]苯氧-4-羟基联苯酮或3,5-二氟-4-羟基联苯酮的自聚缩合合成的,然后通过将PEK分子侧链和末端中存在的50到80摩尔%的氟原子替代为极性基团。此外,可以使用熔融混合技术制造聚醚酮的聚乙烯氯化物混合物,适用于温度为180到120°C的工业用途,并且聚乙烯氯化物与聚醚酮的混合物可应用于高温端用途产品,如热水管道。
