Abstract:
A crystalline fluorine-containing resin composition comprising a melt-processable crystalline fluorine-containing resin and an agent for minimizing spherulite size of a crystalline fluorine-containing resin; said agent being a particle comprising a fluorine-containing multi-segment polymer comprising (A) an amophous fluorine-containing polymer chain segment and (B) a crystalline fluorine-containing polymer chain segment comprising 80 to 100% by mole of tetrafluoroethylene recurring unit and 0 to 20% by mole of a recurring unit represented by the formula (I):CF2=CFâˆ’Rf1â€ƒâ€ƒ(I) wherein Rf1 is CF3 or ORf2, in which Rf2 is perfluoroalkyl group having 1 to 5 carbon atoms.
