There are disclosed a class of halogen-ended polyalkylene glycols and halogen-ended polyolefins (II) which are copolymerizable with polyarylene sulfides or sulfone-based polymers can be easily produced. These halogen-ended polymers may be readily copolymerized with polyarylene sulfides or sulfone-based polymers to provide polyphenylene sulfide copolymers (I) exhibiting increased crystallization speeds. These high crystallization speeds enable the copolymers to be molded in a low-temperature mold, for example, at 100°C or less, while providing fully crystallized moldings having excellent heat resistance properties.
本发明公开了一类卤素端聚亚烷基二醇和卤素端聚烯烃 (II),可与聚芳基砜或砜基聚合物轻松共聚。这些卤素端聚合物可以很容易地与聚芳基砜或砜基聚合物共聚,从而得到结晶速度更快的聚苯硫醚共聚物(I)。这些高结晶速度可使共聚物在低温模具中成型,例如在 100°C 或更低的温度下成型,同时提供具有优异耐热性能的完全结晶模塑物。
