Abstract
Chlorinated rubber containing less than 60 per cent of chlorine, is prepared by the addition to latex of reactants which liberate chlorine in situ. Suitable reactants are hydrochloric acid and an oxidizing agent such as a chlorate, permanganate, bichromate, hypochlorite, or peroxide. The acid may be added to latex stabilized with formalin and saponin, or with formic acid, or to field latex in sufficient quantity to reach the second liquid zone, followed by the addition of a fixed amount of an oxidizing agent, or the oxidizing agent may be added to field latex, and the rubber chlorinated and coagulated by hydrochloric acid subsequently added. Chlorine water also may be employed. The chlorine content of the product may be predetermined by the amount of available chlorine added. Chlorinated rubber containing 1 per cent of chlorine can be masticated and vulcanized with sulphur. As the quantity of chlorine increases the rate of vulcanization with sulphur increases. Products with a chlorine content of 3,8 per cent and upwards are rendered tough and elastic by heating under pressure in the presence of zinc or magnesium oxides, the elasticity decreasing with increase of chlorine.
