Abstract
Abstract Condensation products are prepared by the acid catalyzed condensation of from 1.4 to 2.0 moles of limonene and one mole of phenol. These condensation products can be admixed with an ethylene/vinyl ester copolymer, an ethylene/acrylate ester copolymer, an ethylene/methacrylate ester copolymer or with a mixture of such ester copolymers to form hot-melt adhesive compositions.
