摘要：

A study was made of the possibility of homogenization of PE-PP and PP-ethylene propylene rubber mixtures under shear deformation and high pressure. Films of these heterogeneous mixtures were placed on Bridgman anvils and subjected to shear deformation at a pressure of 0. 1-20 kbar and a temperature of 20 degree C. The structure of initial and deformed films was examined by radiothermoluminescence. The initial films had two glass temperatures, which agree with T//g of the components of the mixture. It is shown that deformation at pressures higher than 1 kbar modifies the phase condition of mixtures.
