AROMATIC ORGANOSULFUR FUNCTIONALIZED 1,4-CIS POLYBUTADIENE

摘要

An aromatic organosulfur-functionalized 1,4-cis polybutadiene is provided to ensure narrow molecular weight distribution, to improve workability of a mixture, elasticity and mechanical property in application to a rubber composition. An aromatic organosulfur-functionalized 1,4-cis polybutadiene has a structure represented by chemical formula 1 or chemical formula 2 which is bonded with the aromatic organic sulfur compound. In chemical formulas 1 and 2, 1, m, n and o show repeating units of a polybutadiene main chain; 1 is 30~99 weight%; m is 0.05~5 weight%; n is 0~50 weight%; o is 0~50 weight%; l+m+n+o=100 weight%; SAr is an aromatic organic sulfur compound; and R1 shows an isocyanate compound.
