Copolymerization of dienic hydrocarbons with alkyl vinyl ethers Communication 1. Effect of carbon tetrachloride on the mechanism of the copolymerization of butadiene with alkyl vinyl ethers

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Summary

  1. 1.

    For the first time it was shown that it is possible for two different copolymerization mechanisms (freeradical and cationic) to coexist in one system.

  2. 2.

    The relative contributions of the free-radical and cationic processes depend on the initial monomer ratio.

  3. 3.

    In presence of the system (benzoyl peroxide + carbon tetrachloride) the copolymerization of butadiene with an alkyl vinyl ether proceeds largely by the cationic mechanism with formation of copolymers containing 85–99% Of the vinyl ether.

  4. 4.

    The occurrence of the cationic process greatly increases the rate of formation of the free-radical copolymer, as compared with the rate of free-radical copolymerization of these components in absence of carbon tetrachloride.
