CRYSTALLINE RESIN CURED PRODUCT, CRYSTALLINE RESIN COMPOSITE BODY AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is a crystalline resin cured product which is excellent in high thermal conductivity, low thermal expansion, high heat resistance, low moisture absorption, gas barrier properties and the like. Also disclosed are a crystalline resin composite body using such a crystalline resin cured product, and their production methods. Specifically disclosed is a crystalline resin cured product obtained by reacting an aromatic glycidyl compound or a glycidyl resin with an aromatic dihydroxy compound or a dihydroxy resin. This crystalline resin cured product has a melting heat of not less than 10 J/g in a differential thermal analysis, and the endothermic peak corresponding to the melting is within the range of 120-320°C. Also specifically disclosed is a crystalline resin composite body which is obtained by combining such a crystalline resin cured product with a filler or a base material. The crystalline resin cured product has a unit expressed as -A-O-CH₂-CH(OH)-CH₂-O-B-, wherein A and B independently represent a divalent aromatic group.
