Title:
HEAT-CURABLE LIQUID-CRYSTAL POLYESTER COMPOSITION AND CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/050850
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat-curable composition capable of curing at a relatively low temperature, and capable of achieving a cured product thereof which exhibits excellent heat-resistance. This heat-curable composition is a heat-curable liquid-crystal polyester composition obtained by melt-mixing a liquid-crystal polyester (A) having a hydroxyl group and/or an acyloxy group at the molecular chain end, and a compound (B) having an intramolecular thermally polymerizable functional group and an intramolecular functional group which reacts with the hydroxyl group and/or the acyloxy group. It is preferable for the liquid-crystal polyester (A) in the heat-curable liquid-crystal polyester composition to have a monomer unit derived from an aromatic compound, an average degree of polymerization of 3-30, and a melting point of 250°C or lower.
