| Abstract: | Photo graft polymerization in the vapor phase of acrylic acid onto the surface of PE film was carried out,taking benzophenone(BP)as photosensit- izer.It was observed that the rate of photo graft polymerization was proport- ional to the concentration of BP.The activation energy of the photo graft polymerization was 4.18kJ/mol.The reaction temperature had little effect on the photo graft polymerization.The graft yield increased both with number of the active hydrogen in PE,and arrangement of the structure in PE. |
