ABSTRACT:
Polycarbamates derived from furfuryl alcohol and certain aromatic di- and polyisocyanates are effective vulcanization accelerators for chloroprene polymers, while at the same time conferring on the polymer compounds exceptional processing safety. These polycarbamates also are virtually nontoxic to experimental animals. Vulcanization of chloroprene polymers is accomplished in the presence of magnesium and zinc oxides, both of which must be present.
