Abstract:
1. A process for producing an aminosilane-functionalized polymer comprising the steps of: (a) providing an initiator formed in situ by mixing at least one type of anionically polymerizable monomer with at least one alkenylaminosilane compound having the formula where n is a whole number selected from the group consisting of 0-2, and m is a whole number selected from the group consisting of 1-3, with the proviso that the sum of m and n equals 3; where each R is independently a hydrogen, alkyl or aryl group; where each R (b) adding at least one metallating agent to the mixture, thereby metallating the alkenylaminosilane and initiating polymerization of the at least one type of anionically polymerizable monomer, thereby producing a polymer that includes at least one aminosilane group at the head of the polymer.
