A study of mechanical properties and structural heterogeneity of polymer networks formed by Photo polymerizations of acrylates monomers

In this paper the structural heterogeneity of phenoxyethyl acrylate (PEA) and an aliphatic urethane acrylate network was investigated. The dynamic mechanical analysis(DMA)was used to determine the distribution of relaxation times of the networks as a function of each component composition of the copolymer. DMA analysis confirms the existence of 2 regions: rich of oligomer and poly phenoxyethyl acrylate plasticized with monomers
