Styrenated Terpene Resin is made by carrying out cationic polymerization of a terpene compound and sytene compound under Friedel-Crafts catalyst, in processing of the hydrolysis, washing, filtering and distillation to be the linear polymer. It is easily solved in all kinds of elastomeric polymer like styrene-butadiene block copolymer, natural rubber and styrene-butadiene rubber. Styrenated Terpene Resin is widely used in rubber, coating and adhesive industries, especially for hot melt adhesive.
