Abstract

Abstract:

The corn starch was acidthinned and oxidized，then grafted copolymerization acrylamide，so composite modified starch is synthesized. By examining the effect of each element on G(grafting percentage) and GE(grafting effection) of graft copolymerization production，the condition of graft copolymerization reaction were determined：50 ℃ of graft reaction temperature，3 h of reaction time，0.8 of the mass ratio of starch to acrylamide. By validating test of technology condition for composite modified starch and analysis on its physical and chemical properties，composite modified starch suitable for preparing wood adhesive was testified.

Key words: acidthinned and oxidized corn starch, grafting copolymerization, characterization
