Agent for minimizing size of spherulite of crystalline fluorine-containing resin and crystalline resin and crystalline fluorine-containing resin composition comprising said agent

摘要

Spherulites in a molded article obtained from a melt-processable crystalline fluorine-containing resin composition are minimized to give the transparent molded article having a smooth surface and being resistant to contamination. An agent for minimizing spherulite size which comprises an amorphous fluorine-containing polymer or a fluorine-containing multi-segment polymer. The fluorine-containing multi-segment polymer comprises an amorphous segment and a crystalline segment.
