COMPOUND FOR HEAT-RESISTANT LAMINATE, AND PRODUCTION OF HEAT-RESISTANT LAMINATE

摘要

PURPOSE:To provide the title compd. excellent in heat resistance, moisture resistance, and storage stability by using a specific imide compd. as the main component. CONSTITUTION:The title compd. mainly comprises a compd. of formula I wherein Ar1 is a same or different tetravalent arom. group; Ar2 is a same or different divalent arom. group; X is a same or different trivalent linkage selected from formulae II, III, and IV; n is 0-15; and R is a reactive group. The compd. is dissolved in an org. solvent to give a varnish, which is applied to or impregnated into a reinforcing material and dried to a specified residual-solvent concn. to give a prepreg. At least one sheet of the prepreg is sandwiched between two sheets of copper foil and integrally molded by thermal pressing, thus giving a double-side copper-clad laminate. Post-curing is effective in improving the heat resistance and mechanical strengths of the laminate.
