抄録

In the presence of a metal chloride (as catalyst)-halo-organic compound (as co-catalyst) system, liquid rubbers such as Hycar 1312, Neoprene FB and Frosbrene, were found to crosslink to give solid vulcanizates at ordinary vulcanization temperature. In the absence of the co-catalyst, however, they afforded no satisfactory vulcanizate except Neoprene FB. The curing system of stannous chloride-benzotrichloride was one of the active one′s. For example, the compound of 100 parts of Flosbrene MV with 4 to 6 parts of SnCl2•2H2O and 5 parts of benzotrichloride was cured at 142.8°C. to give a vulcanizate with 94 to 100° Shore hardness.<br>Many sorts of catalyst-co-catalyst systems for liquid rubbers were tested and some mechanisms of such crosslinking reactions were suggested.
