Abstract: This paper deals with the polymerization process of high softening point terpene resin. Through laboratory experiments, a complex catalytic system has been selected and suitable reaction conditions determined, providing some reliable data for further industrial testing. With rich superfine turpentine from Pinus massoniana as raw material and methylbenzene as reaction solvent, terpene resins (Softening point>110) in light colour (Gardner’s color< 6 ) can be obtained by cationic polymerization in the temperature range of o?5- with anhydrous A1C13 as catalyst and suitable amount of auxo-catalyst, after the procedures of hydrolysis, filterization, washing and distillation, etc. The yield rate of solid resin is above 70% of weight of the turpentine raw material used.
