Claim:
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 C 1 -C 10 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 R 1 , OR 1 , OC(O)R 1 , C(O)OR 1 or NR 1 2 in which each R 1 independently is a C 1 -C 30 alkyl group, thereby providing said terminal functionality to said polymer.
