GRAFT POLYMERIZATION METHOD FOR POLYMERIC BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a simple and practical vapor phase graft polymerization method in which the problem of uneven graft is eliminated by eliminating problems with regard to the vapor phase graft polymerization. SOLUTION: The vapor phase graft polymerization method includes the step of bringing an irradiated organic polymeric base material into contact with the vapor of a polymerizable monomer to carry out a graft polymerization. The graft polymerization reaction is carried out in the state where the polymeric base material is folded or wound with a space between the adjacent polymeric base materials.
