Abstract: The technology to prepare copolymeric resins was described by use of α-pinene(α-P) and 1,3-pentadiene(PD) as monomers and Louis acid as the catalyst. The effect of reaction temperature, reaction time, catalyst concentration, ratio of α-pinene to 1,3-pentadiene on copolymerization was discussed. The optimized reaction condition is as follows: reaction temperature 15 ℃, reaction time 2 h, solvent toluene， m(catalyst)∶m(α-P and PD)=1%, n(α-P)∶n(PD)=1∶2. The product yield, softening point, Chroma, Mn, and relative molecular mass distribution（MWD） are 72.5%, 121.3 ℃, 4, 1549, and 1.92, respectively. The product has good thermal stability and adhesion compatibility.
