Structure and properties of binary mixtures polystyrene-epoxyacrylic oligomers irradiated by electrons

Using the methods of birefringence, isometrical heating, IR-dichroism and thermal optical analysis change in structure of oriented polymer-oligomer systems on the base of PS (M>106) and epoxyacrylic (EA) oligomers of aliphatic and aromatic structure is studied during the process of irradiation by fast electrons. Their mechanical properties are studied and it is established that introduction of aliphatic epoxyacrylate to PS and subsequent irradiation allow to obtain composite materials with higher values of strength, modulus of elasticity and softening temperature in isotropic and oriented states. 6 refs., 2 figs., 3 tabs
