Abstract
PURPOSE: To simply modify the title resin, enhancing curing property thereof, by compounding a novolak obtained by the reaction of resorcinol or its mixture with other phenol, with a specified amount of HCHO, and a novolak-type phenol resin.
CONSTITUTION: Resorcinol alone or its mixture with an other phenol, is reacted with 0.5W0.95mol, per mol of the tolal of the phenols, of HCHO. The obtained resorcinol novolak has resorcinol residues at the both terminals, in either case. 5W50wt% as a solid of at least one of resorcinol novolaks obtained, is compounded with a novolak-type phenol resin. Thus it is possible for the novolak-type phenol resin to reduce curing time and to lower curing temperature.
