The starch acetate membranes were cast with different solvents,namely,dichloromethane,chloroform,acetone and 1,4-dioxane. The effects of casting solvents on membrane compactness,crystallinity,water-resistance,and degradation in soil were investigated.

• 以醋酸酯型改性淀粉(简称醋酸酯淀粉)为原料；分别以二氯甲烷、三氯甲烷、丙酮和1；4-二氧六环为铸膜液溶剂；用浇铸法制备醋酸酯淀粉膜；并研究了铸膜液溶剂对膜致密性、膜结晶度、膜耐水性及膜在土壤中降解速率的影响.
