Sulfenyl halide polymerization terminators |
摘要 |
<p>A method of preparing a functionalized polymer comprising the steps of initiating the formation and propagation of an anionically-polymerized living polymer, and terminating the propagation of the living polymer by reacting the polymer with a terminating agent selected from the group of agents defined by the formulas (III), (IV), and (V) <CHEM> where C is a carbon atom, S is a sulfur atom, X is a halogen atom, R2 and R4 are independently selected from hydrogen and carbon-based moieties, and where the phenyl groups are selected from unsubstituted and substituted phenyl groups.</p> |
