The polymerization of P-pinene with the A1Cl3/SbCl3 binary catalyst was investigated in toluene a t -40°C and was compared with that of a-pinene. The polymerization of P-pinene with AlC13 alone was very rapid and retarded on addition of SbC13, in sharp contrast to that of a-pinene where added SbC13

a-End-functionalized polymers and macromonomers of b-pinene were synthesized by living cationic isomerization polymerization in CH 2 Cl 2 at 040ЊC initiated with the HCl adducts [1; CH 3 CH(OCH 2 CH 2 X)Cl; X Å chloride (1a), acetate (1b), and methacrylate ( 1c)] of vinyl ethers carrying pendant sub
Cationic polymerization of styrene(St) initiated by phosphorus trichloride(PC13) in nitrobenzene was carried out at 30 °. The initial rate was proportional to [St] 2 and [PCl3]. The overall activation energy was about 10.4 kcal/mole. The rate and the degree of polymerization were enhanced with incre
