在硫氰酸钠浓水溶液中丙烯腈-酪素接枝共聚的研究

Study on Graft Copolymerization of Acrylonitrile onto Casein in Concentration Aqueous Solution of Sodium Thiocyanate

采用傅利叶红外光谱表征了在硫氰酸钠(NaSCN)浓水溶液中丙烯腈(AN)、酪素(Casein)均相接枝共聚制得的接枝共聚主产物为AN—g—Casein接枝共聚物,研究了反应时间、单体质量分数、引发剂质量分数、反应温度对接枝共聚的影响,讨论了反应前酪素的溶解条件。

The main products of graft copolymerization of acrylonitrile onto casein in concentration aqueous solution of sodium thiocyanate at homogeneous phase are characterized as a AN - g - Casein graft copolymer by FTIR. The effects of the reaction time, monomer conentration, initiator concentration and reaction temperature on copolymerization are investigated . The condition of solution process of casein before reaction is discussed.
