PURPOSE:To provide the subject particles suitable for the returnable cases of mechanical parts. oily food containers, etc., and having excellent foamability in a short time by coating or impregnating a fluorine-containing vinylic polymer obtained by polymerizing a specific fluorine-containing vinylic monomer. CONSTITUTION:The objective resin particles are produced by coating or impregnating a fluorine-containing vinylic polymer obtained by polymerizing a fluorine- containing vinylic monomer of the formula [Rf is CaF2a+1 ((a) is 1-16); R1 is (CnH2nO)m, C1H21 ((n), (m) are 1-10; (1) is 1-12); R2 is H, CH3, COOCH2CH2R4 [R4 is CbF2b+1 (b=1-16)]; R3 is H, COOCH2CH2R5 [R5 is CqF2b+1 ((q) is 1-16)]. |
