Process for preparing granular chloroprene polymer rubber

摘要

This invention relates to a novel process of preparing chloroprene polymer rubber granules. The process comprises adding 4 to 10 wt. parts of sodium silicate to 100 wt. parts of a cationic latex of chloroprene polymer and then adding an alkaline earth metal salt or an acid to precipitate granules of the chloroprene polymer rubber.
