<p><P>PROBLEM TO BE SOLVED: To provide a nucleating agent for polylactic acid promoting crystallization of polylactic acid and improving heat resistance and moldability, and a polylactic acid resin composition using the nucleating agent. <P>SOLUTION: When nicotinic acid hydrazide is reacted with sebacic acid dichloride, dihydrazide (II) shown in figure is obtained. When a small amount of the dihydrazide (II) is added to polylactic acid, excellent crystallization promotion action is exhibited, and crystallization temperature is increased. Therefore, heat resistance and moldability of a polylactic acid resin can be improved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
