摘要
用甘油／尿素／甲酰胺复合增塑剂对玉米淀粉进行增塑处理制成了可塑性淀粉．研究了复合增塑剂中醇和酰胺的配比对可塑性淀粉力学性能的影响．结果表明，醇／酰胺复合增塑剂可赋予淀粉可塑性，两类增塑剂之间存在着协同效应，最佳协同配比为3／7～4／6．
The plastic starch was made of corn starch plasticized by urea, formamide and glycerol. The mechanical properties of plastic starch made of com-plasticizer in different formulation were studied. The results showed that corn-plasticizer containing alcohol and amide can plasticize starch, alcohol-plasticizer and amide-plasticizer have synergy in plasticizing efficiency, the best synergic ratio was between 3/7 and 4/6.
