FULLY AROMATIC POLYESTER AND POLYESTER RESIN COMPOSITION

Title:

FULLY AROMATIC POLYESTER AND POLYESTER RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2012/137636

Kind Code:

A1

Abstract:

The present invention provides a fully aromatic polyester that can be produced in a normal polymerization device and that has superior heat resistance and ductility. The fully aromatic polyester comprises: a constituent unit (I) derived from 4-hydroxybenzoic acid; a constituent unit (II) derived from 6-hydroxy-2-naphthoic acid; a constituent unit (III) derived from 1,4-phenylene dicarboxylic acid; a constituent unit (IV) derived from 1,3-phenylene dicarboxylic acid; and a constituent unit (V) derived from 4,4'-dihydroxybiphenyl. The fully aromatic polyester exhibits optical anisotropy when melted and, with respect to all the constituent units, there are 35-75 mol% of constituent unit (I), 2-8 mol% of constituent unit (II), 4.5-30.5 mol% of constituent unit (III), 2-8 mol% of constituent unit (IV), 12.5-32.5 mol% of constituent unit (V), and 4-10 mol% of constituent units (II)+(IV).
