Patent

CA 2027409

There are disclosed a class of halogen-ended poly-alkylene 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.
