CRYSTAL NUCLEATING AGENT CAPABLE OF USING FOR A POLYLACTIC ACID RESIN AFTER ADJUSTING THE PARTICLE SIZE OF SPECIFIC AROMATIC SULFONATE, AND A POLYLACTIC ACID RESIN COMPOSITION USING THEREOF

摘要

PURPOSE: A crystal nucleating agent for a polylactic acid resin, and a polylactic acid resin composition using thereof are provided to improve the crystallization of the polylactic acid resin with the low optical purity.;CONSTITUTION: A crystal nucleating agent for a polylactic acid resin is a crushed material of aromatic sulphonic acid salt marked with chemical formula 1. In the chemical formula 1, X is a moiety in which 3 hydrogen atoms are removed from benzene. R1 and R2 are a hydrocarbon group with the carbon number of 1~6. M is either an alkali metal atom or an alkali earth-metal atom. N is 1 when the M is the alkali metal atom, and 2 when the M is the alkali earth-metal atom.;COPYRIGHT KIPO 2010
