| Abstract: | In this communication, anionic telomerization of butadiene and isoprene with n-BuLi as the initiator, potassium dimethylphenoxide (D-ROK) as the promoter, xylene as the transfer agent as well as the solvent in the presence of diglycoldimethylether (2G) as the polar modifier was studied. Solubility of D-ROK in tetrahydrofuran (THF) at different temperature was investigated. Effects of D-ROK / n-BuLi on intrinsic viscosity (η]), chain transfer number (Nt), relative molecular mass (Mn) and microstructure of the polymers were examined. Raising D-ROK / n-BuLi, resulted in increasing of Nt and deceasing of η] and Mn. Liquid rubber produced this way can be used as material for green coating. |
