Abstract

PURPOSE: To coagulm of chloroprene polymer containing volatile substances obtained from chloroprene polymer latex is combined with a specific amount of alkali metal carbonate and dried to produced chloroprene rubber of high storage stability and processing stabiliy.
CONSTITUTION: Chloroprene polymer latex is brought into contact with an alkali metal or alkaline earth metal to break the emulsion of the latex to coagulate the polymer and obtain coagulm. The coagulm is dehydrated by pressing in a screwtype extruder, then 0.01W10pts. wt., preferably 0.03W5pts. per 100pts. of the chloroprene polymer, of an alkali metal carbonate such as sodium carbonate are added to the coagulm, Further, volatile substance, mainly consisting of water, is evaported and dried to give chloroprene rubber.
