Improvements in catalysts for aqueous emulsion polymerizations. Us Rubber Co, May 25, 1960: GB835674-A (2 worldwide citation)

A polymerization catalyst comprises a metal borohydride to which may be added a watersoluble cobaltous, nickelous, manganous, ferrous or cuprous salt which forms a precipitate with the borohydride. The borohydride may be of an alkali or alkaline earth metal, thorium, mercury, gold or lead. The examp ...
