The accelerating activity of N,N-substituted aminoethyl methacrylates on the curing of methyl methacrylate and composite resins with benzoyl peroxide is somewhat smaller than that of dimethyl-p-toluidine. Resins cured with aminoethyl methacrylates containing a p-tolyl and 3,5-xylyl substituent on the nitrogen atom turned approximately the same color in ultraviolet light as resins cured with dimethyl-p-toluidine. The incorporation of the predominant part of an unsaturated tertiary amine into polymer chains reduces to a minimum the possibility of its diffusion from the resin into the surrounding tissue.
