PURPOSE:To prepare a resin compsn. used for a laminate and excellent in the heat resistance, mechanical strengths, and adhesive properties by compounding a compsn. obtd. by compounding a specific polyfunctional epoxy resin with a bismaleimide compd.-arom. diamine condensate with a specific linear polymer. CONSTITUTION:A resin compsn. for a laminate is prepd. by compounding 100 pts.wt. compsn. (A) obtd. by compounding 100 pts.wt. polyfunctional epoxy resin of formula I (wherein (m)/(n) is 1 to 10 or (n)=0; and (a) is 1 or 2) with a mol.wt. of 1000 to 3000, obtd. by glycidylating a polycondensate of a mixture of a brominated bisphenol A with bisphenol A or the brominated bisphenol A only with formaldehyde, with 10 to 40 pts.wt. condensate obtd. by reacting one mol of a bismaleimide compd. with 0.2 to 1.3mol of an arom. diamine; and 1 to 60 pts.wt. linear polymer (B) having a mol.wt. of 5000 to 100000 and compatible with compsn. A (e.g. polysulfone, polyethersulfone, or polyester). |
