摘要
Polyisoprenes predominantly composed of cis-1,4- units are studied by the methods of NMR spectroscopy (600 MHz), GPC, and DSC. A comparative investigation of synthetic polyisoprene and natural rubbers shows that a small (up to 3-4 mol %) amount of polymer-chain disruptions, such as inverse additions of cis-1,4 units and units occurring in 3,4- and trans-1,4-configurations, has no effect on the local conformational structure of the polymer.
