<p>PURPOSE:To obtain the titled composition having improved flexibility, cracking resistance and heat aging resistance, by adding a specific acrylic polymer to a phenolic resin, and removing the solvent and water under heating. CONSTITUTION:An acrylic polymer having a viscosity of 0.9cps or higher and lower than 3cps, preferably 1cp or higher and lower than 2.5cps, in a 5% solution in ethyl acetate at 25 deg.C in a solution, suspension or solid state is added to a phenolic resin, heated at 80-160 deg.C and then melt mixed while removing the solvent and water out of the system. USE:A general molding material, laminating material, etc.</p> |
