A number of di- and triacrylates and methacrylates containing silicon have been prepared. In the presence of a photoinitiator and absence of a tertiary amine, these compounds photopolymerized to give thin films, and in some cases this was not accompanied by shrinkage. The rate of polymerization, as judged by the amount of exposure to give tack-free coatings, was usually found to be much greater than standard diluents such as hexanediol diacrylate, tripropyleneglycol diacrylate and trimethylolpropane triacrylate. Monitoring the degree of cure by quantifying the extent to which the acrylate or methacrylate groups have been utilized showed that the presence of silicon affected the extent to which double-bond utilization occurs.
