Functionalized Polymer

摘要

A method for providing a polymer having terminal functionality involves reacting a terminally active polymer with an α,β-ethylenically unsaturated compound that includes a group 2-13 element so as to provide a functionalized polymer. The resulting polymer exhibits enhanced interactivity with particulate fillers and can be used in the manufacture of vulcanizates.

1. A method of providing terminal functionality to a polymer, said method comprising reacting a terminally active polymer that comprises polyene mer with an α,β-ethylenically unsaturated compound having the general formula where each R independently is a hydrogen atom or C1-C10 alkyl group, M is a group 2-13 element, y and z are integers with the provisos that z is not zero and y+z is equal to a valence of M, and each X independently is R1, OR1, OC(O)R1, C(O)OR1 or NR12 in which each R1 independently is a C1-C30 alkyl group, thereby providing said terminal functionality to said polymer.
