Synthesis and Capability on Grafting Membrane of PVC With Acrylic Acid

The PVC membrane grafted with acrylic acid was conducted by using (NH 4) 2S 2O 8 as initiator and a series of grafted membranes having different grafting yield were synthesized,the effect of monomer content and initiator content on grafting yield was analyzed. It was found that the synthetic film was just acrylic acid/PVC grafting membrane by FT_IR Spectrum. Tensile experiment showed grafted acrylic acid could improve strength of the film.
