摘要： PURPOSE: An amphoteric starch is provided to have uniform viscosity stability according to time in comparison with existing corn starch and cationic corn starch, and to improve physical properties of paper of corn starch. CONSTITUTION: An amphoteric starch can be obtained by substitution-reacting normal starch or modified starch by using an anionic monomer and cationic monomer, and accepts anions and cations at the same time. A manufacturing method of the amphoteric starch comprises: a step of adding anionic monomers in to 20-50 wt% of starch; a step of controlling the moisture in the reactant to 5-20 weight% by removing moisture through dehydration and/or drying process; and a step of adding cationic monomers in the moisture condition.

摘要： A starch which has been esterified and grafted with a polyester. The esterifying acid is at least one member selected from among saturated and unsaturated C2-18 fatty acids and aromatic carboxylic acids. The polyester is a polymer prepared by the ring opening of at least one member selected from among lactones with 4- to 12-membered rings, and the terminal hydroxyl group thereof is substantially blocked with an ester group. A molded article obtained from the starch can easily achieve the desired flexibility and a toughness on a practical level and has moisture-related characteristics on a practical level, even when it contains no or little plasticizer.
摘要翻译：一种已被酯化并用聚酯接枝的淀粉。酯化酸是选自饱和和不饱和C2-18脂肪酸和芳族羧酸中的至少一种。聚酯是通过选自具有4至12元环的内酯中的至少一种的开环而制备的聚合物，并且其末端羟基基本上被酯基封端。由淀粉得到的成型品即使在不含有或者不含增塑剂的情况下，也能够容易地在实用水平上实现期望的柔软性和韧性，并具有实用水平的与水分有关的特性。

摘要： A starch derivative which, when incorporated with no or only a little plasticizer, yields moldings having good flexibility, toughness, and water-relating properties for practical use comprises an esterified, polyvinyl ester-grafted starch derivative which is formed by esterifying starch and grafting starch with a polyvinyl ester. The polyvinyl ester is derived from one or more saturated or unsaturated aliphatic acids or aromatic carboxylic acids having 2 to 18 carbon atoms.
