✦ Synopsis
A review about the accelerating e †ect of tertiary aromatic amines used as activator in the benzoyl peroxide/amine system for the curing of acrylic resins is presented. The kinetics, mechanism and activation energy of the reaction are considered, together with some toxicity, residuals and leaching data concerned with biomedical applications of this system, e.g. denture resins or acrylic bone cements. Furthermore, some results relating the e †ect of the temperature of the surroundings on the curing parameters of the cements prepared with three amines (N,N-dimethyl-4-toluidine, N,N-dimethylbenzyl alcohol and N,Ndimethylbenzyl methacrylate) are shown. The results indicate that the temperature has a signiÐcant e †ect on the curing parameters, and must be considered in the evaluation of new activators. The relevance of these results lies with the importance of thermal trauma generally associated with the implantation of acrylic bone cements.
