METAL ION NEUTRALIZED N-SUBSTITUTED MALEIMIDE/MALEIC ACID/OLEFIN COPOLYMER, TRANSPARENT RESIN COMPOSITION, AND TRANSPARENT FILM

摘要

PROBLEM TO BE SOLVED: To provide a metal ion neutralized N-substituted maleimide/maleic acid/olefin copolymer excellent in transparency, rigidity, and surface hardness and capable of appropriately using as an optical film etc.;SOLUTION: This metal ion neutralized N-substituted maleimide/maleic acid/olefin copolymer is an N-substituted maleimide/maleic acid/olefin copolymer comprising 39.9-60 mol% N-substituted maleimide residue unit, 60-39.9 mol% olefin residue unit, and 10-0.1 mol% maleic acid residue unit, and 30-90 mol% carboxylic group derived from the maleic acid residue unit in the N-substituted maleimide/maleic acid/olefin copolymer is neutralized by a metal ion.;COPYRIGHT: (C)2007,JPO&INPIT
