Notes:
Conditions for the convenient synthesis of linear poly(β-pinenes) that carry one or two tert-chloro end groups (∼Clt) and three-arm star poly(β-pinenes) that carry three termini have been worked out. Specifically, the polymer with one ∼Clt end group was prepared by the H2O/BCl3 system, whereas those with two and three ∼Clt termini were prepared by the use of p-dicumyl chloride and sym-tricumyl chloride/BCl3 inifer combinations. The ∼Clt-terminated polymers were dehydro-chlorinated to yield the corresponding olefins. The molecular weights of the products were low enough to permit infrared (IR) and quantitative 1H-NMR investigations. Poly(β-pinene-b-tetrahydrofuran) diblock copolymers have been synthesized by inducing the polymerization of tetrahydrofuran (THF) by the Pβ—Clt/AgCF3SO3 initiating system.
