Abstract

Abstract: The grafting mixtures were meatqured by a slab method of sodium dodecyl sulphate-polyacrylamide gel electrophoresis(SDS-PAGE).It was proved by this test that all ingredients in gelatin(α_P,α,β,γ,γ_p)could be grafted with ethyl acrylate and most gelatin molecules were converted into grafting copolymers whose M_nwas much more than 3×10⁵.This conclusion and the chracterization of grafting percentage or grafting efficiency from the SDS-PAGE patterns were similar to those from usual quantitative analysis in this paper.
