Abstract

262,179. Beckmann, H. Sept. 2, 1925. Addition to 240,430. Latex, coagulating. - Indiarubber having microscopically small pores is obtained by coagulating latex to a homogeneous cohesive jelly and vulcanizing this without allowing it to become dry. The coagulation is effected either by treating the latex with a gaseous acid, such as sulphurous acid, or by converting it into a thick, paint-like pulp by the admixture of alum, zinc sulphate, ferric chloride, or the like and eubsequently coagulating with a liquid or gaseous acid.
