![عکس صفحه اول مقاله: Adhesion of olefin block copolymers to polypropylene and high density polyethylene and their effectiveness as compatibilizers in blends Adhesion of olefin block copolymers to polypropylene and high density polyethylene and their effectiveness as compatibilizers in blends](/preview/png/5185032.png)
Adhesion of four ethylene-octene block copolymers (OBCs) to polypropylene (PP) and high density polyethylene (HDPE) was studied by peeling PP/OBC/HDPE microlayered tapes. The four OBCs had different comonomer composition, mechanical properties and phase morphology. Through the Irwin damage zone analysis, it was found that the stress-strain behavior of OBC was the primary factor that determined the adhesion strength. Effectiveness of these OBCs as compatibilizers in PP/HDPE blends was also investigated. Toughness of all OBC-compatibilized blends was effectively improved. The OBCs having higher adhesion strength also resulted in better mechanical performance for the compatibilized blends. A quantitative correlation was established between the adhesion strength and mechanical performance of the blends.
