Macromolecular compounds Communication 58. Steric hindrance in the polymerization of nuclear-substituted styrenes

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

Summary

  1. 1.

    It is shown that the isoporpyl group in the ortho position of the styrene molecule does not cause steric hindrance in the polymerization process.

  2. 2.

    It is shown that 2-methoxyl groups in the ortho position of the styrene molecule do not hinder polymerization.

  3. 3.

    2,4,5-trisopropylacetophenone and 2,4,5-triisopropylstyrene have been synthesized.

  4. 4.

    Polymers of 2,4,5-triisopropylstyrene and 2,6-dimethoxystyrene have been prepared.

  5. 5.

    An explanation based on stereoehemical grounds is given for the absence of steric hindrance in the polymerization of 2,4,5-triisopropylstyrene and 2,6-dimethoxystyrene; an explanation is also given for the occurence of steric hindrance in the polymerization of 2,6,dimethyl-4tertiarybutylstyrene and 2,4,6-tri- ( fluoromethyl)styrene.
