Abstract
Artificial caoutchouc is freed from unstable chlorine by treatment with water or steam at ordinary or raised pressure in presence of hydroxides, carbonates, or other substances neutralizing hydrochloric acid. Mixtures of the product with natural caoutchouc are then readily vulcanized in presence of accelerators. For example, 1000 kg. of sulphurized oil is well damped with water, 30 kg. of chalk are added, and the whole steamed at 3 atmospheres for 2,5 hours; the water is drained off and the caoutchouc dried. 70 kg. of the product mixed with 100 kg. of rubber, 50 kg. of lithopone, 30 kg. of zinc-white, 4 kg. of sulphur, and 0,5 kg. of accelerator, vulcanizes well at 145 DEG C. in 15-20 minutes.ALSO:Artificial caoutchouc is freed from unstable chlorine by treatment with water or steam at ordinary or raised pressure in presence of hydroxides, carbonates or other substances neutralizing hydrochloric acid.
