The gelling doses of polyethylene, polymethyl acrylate, and polyvinyl acetate are significantly decreased by small additions of triallyl cyanurate (TAC). Though larger additions of TAC inhibit gel formation at low doses, at higher doses gel formation is considerably increased. An estimate of the cross- linking efficiency of TAC in polyethylene leads to the conclusion that at concentrations between 0.5 and 5.0%, each additive molecule cross-links to between 2.5 and 3 polymer molecules, indicating that reactions such as hydrogenation or polymerization of the allyl groups are insignificant in this concentration range.
