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 |
