Abstract
PURPOSE: To obtain the titled compsn. which exhibits excellent workability during kneading, by a method wherein a solution of a vulcanizing component such as a polyhydroxy compd. in a water-soluble org. solvent is added to an aq. dispersion of a fluorine-contg. rubber, a coagulating agent is added to the mixt., and the resulting coagulated compsn. contg. the vulcanizing component and the rubber is isolated.
CONSTITUTION: In a process for isolating a fluorine-contg. rubber by coagulating the rubber from an aq. dispersion thereof and then isolating the rubber, a solution in a water-soluble org. solvent of a vulcanizing component such as a polyhydroxy compd. (e.g. resorcinol or 1,3,5-trihydroxybenzene) or a mixt. of the polyhydroxy compd. and a quaternary compd. contg. nitrogen or phosphorus [e.g. the compd. of formula I or II (wherein R' is 1W20C alkyl, R2 is 1W20C alkyl, etc.; R3 is 1W21C alkylene, etc.; X is an anion such as a halide, etc.; Y is nitrogen or phosphorus], is added to the aq. dispersion of the fluorine-contg. rubber. A coagulating agent is added to the resulting mixt. to coagulate a compsn. contg. the vulcanizing component and the fluorine-contg. rubber. Then the compsn. is isolated. In this way, there can be obtd. the titled compsn. in which the vulcanizing component is uniformly dispersed in the fluorine-contg. rubber.
