摘要:
It is shown that the deformation of high-density polyethylene films in poly(ethylene oxide) solutions occurs via the delocalized-crazing mechanism and leads to the formation of polymer blends. With an increase in the draw ratio, the concentration of poly(ethylene oxide) in the blend increases and significantly exceeds the theoretical values calculated from the polyethylene porosity and the poly(ethylene oxide) concentration in the solution. It is suggested that the high concentration of poly(ethylene oxide) in the blends is due to its adsorption on a highly developed surface of polyethylene deformed via the crazing mechanism. The composition of the resulting blends is independent of the strain rate.
