Abstract

A new efficient method for the synthesis of soluble thermoplastic polymers of isoprene with softening points in the range from 73 to 160°C has been developed. The method consists in the cationic polymerization of isoprene in dichloromethane or toluene in the presence of catalytic systems based on triethylaluminum in combination with tert-butyl chloride, tert-butyl bromide, 2-chloro-2-methylbutane, or isopropyl chloride.

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
