Mechanical Properties of Poly[Methyl Acrylate-2-(Dimethylamino)ethyl Methacrylate]/Epoxy Resin IPN

Abstract

Abstract: Simultaneously interpenetrating polymer networks were prepared from polyrmethyl aery-late-2-(dimethylamino)ethyl methacrylate]/epoxy resin [P(MA-DMA)/EP]. Mechanical properties of IPNs were measured. Asingle glass transition teinperature and a better compatibility were observed. This shows that the sample is the mixed polymer of cross-linking and interpenetrating networks. When P(MA-DMA)/EP= 20/80, there exists positive synergistic. effect. (T_g)_calcdwas calculated by Fox equation and it was found that (T_g)_exp-(T_g)_calcdwas proportional to (d_exp-d_caled). Moreover, the value of (T_g)_exp-(T_g)_caicdcan represent approximately the ratio of interpenetrating to cross-linking.
