POLYLACTIC ACID COMPOUND, ITS MANUFACTURING METHOD, POLYLACTIC ACID COMPOUND COMPOSITE MATERIAL AND MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid compound which has a sufficiently high rate of crystallization and is prevented from staining due to bleeding out and causing slippage of pellets with one another, its manufacturing method, a polylactic acid compound composite material, and a molded product composed of the polylactic acid compound composite material.;SOLUTION: The polylactioc acid compound has a weight average molecular weight of 5,000-400,000 and at least one structure represented by formula (1) (wherein m is an integer which allows the obtained compound to have a weight average molecular weight of 5,000-400,000) and at least one structure represented by formula (2), the structure represented by formula (1) being bonded to the structure represented by formula (2) through a 1-25C alkylene group, and terminal groups of at least one kind selected from the group consisting of hydrogen, a hydroxy group, and a 1-25C alkyl group.;COPYRIGHT: (C)2005,JPO&NCIPI
