Abstract
Modified resorcinol polymers are prepared by mixing acid or base with liquid phenol-resorcinol resin, permitting the mixture to stand for a period of at least about 48 hours followed by separation of an aqueous solution from the resin to recover the resorcinol polymer. The modified resorcinol has improved physical characteristics when employed in molding compositions, coating compositions and the like.
