Influence of Regulator, Temperature and Monomer Proportion on the Microstructure and Sequence Distribution of Random Isoprene-styrene Copolymer

摘要

The linear random isoprene-styrene copolymer (L-SIR) was prepared by solution polymerization with cyclohexane - n-hexane mixture as solvent and n-BuLi as initiator in the presence of the polar regulator - tetrahydrofuran (THF). Microstructures of L-SIR have been studied by ~1H-NMR.
