Abstract
PURPOSE: An aqueous dispersion of fluorine rubber is combined with a salt of polyhydroxy compound as a vulcanizer and they are incorporated with an acid to cause coagulation and separation, thus producing a composition containing uniformly dispersed vulcanizer and showing remarkably improved kneading operability.
CONSTITUTION: As a vulcanizing agent, a salt of polyhydroxy compound, preferably an alkali metal salt, is added to an aqueous dispersion of fluorine rubber, preferably of about 5W50wt% concentration, and further a quaternary compound of nitrogen or phosphorus is added as a crosslinking accelerator. Then, an acid is added to convert the salt of polyhydroxy compound into the free form and coagulate and separate the composition composed of fluorine rubber and vulcanizer. When needed, a coagulant is added.
