MODIFIER FOR RESINS, ADHESIVE COMPOSITIONS, AND THERMOPLASTIC RESIN COMPOSITIONS

摘要

The present invention provides a resin modifier comprising as an active ingredient a hydrogenated rosin ester in which a component having a molecular weight of 320 of a methylation product of a hydrolyzate of the hydrogenated rosin ester as measured by gas chromatography-mass spectrometry accounts for 95 wt % or greater of the total amount of the components having a molecular weight of 314 to 320; a modifier that is an optical embrittlement inhibitor for use in an adhesive polymer resin; an adhesive composition comprising the optical embrittlement inhibitor; a modifier that is a melt fluidity and adhesion improver for a thermoplastic resin; and a thermoplastic resin composition comprising the melt fluidity and adhesion improver.
