NOVEL POLYCARBOXYLIC ACID ANHYDRIDE AND USE THEREOF

摘要

The present invention relates to a polycarboxylic acid anhydride having a structural unit represented by the following Formula (1). The present invention provides a novel polycarboxylic acid anhydride. When the polycarboxylic acid anhydride is used, for example, as an epoxy resin-curing agent, the balance of the composition of the resin composition is stabilized, and a resin molded article having excellent heat resistance, transparency, thermal yellowing resistance, surface hardness, solvent resistance, flexibility, and adhesiveness is thus provided.;

主权项

1. A polycarboxylic acid anhydride having a structural unit represented by Formula (1): wherein Rx represents a cycloalkylene group or a group in which two or more cycloalkylene groups are bonded by a single bond or a divalent group, the cycloalkylene group being optionally substituted; R1 to R10 are identical or different and each represent hydrogen or optionally substituted alkyl; and two groups among R1 to R10 may together form a divalent group.
