| Abstract: | Poly(vinyl chloride)-g-poly(2-hydroxyethyl methacrylate) (PVC-g-PHE MA) copolymers were prepared by the aqueous suspension-swelling graft copolymer ization process.The grafting of HEMA on PVC was confirmed by the infrared spect rum.The grafting degree increased with the increase of feeding mass fraction of HEMA,and a maximum grafting efficiency appeared at 10% mass fraction of HEMA i n feed.The grafting degree and efficiency increased as partially dehydrochlorin ated PVC was used.The intrinsic viscosity of graft copolymers increased slowly with the increase of the grafting degree of HEMA,and decreased at high grafting degrees.PVC-g-PHEMA copolymers exhibited a higher glass transition tempe rature (T g) in the first DSC run than that in the second run,and T g of graft copolymers increased as the grafting degree increased. |
