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.
