Abstract:
A functionalized polymer can be prepared by a process that includes reacting (a) an ethylenically unsaturated reactant polymer which, at its terminus, includes Si-containing repeat unit(s) with (b) one or more silanes, at least one of which includes at least one primary amine, secondary amine, phosphine, hydroxyl, thiol, cyano, urea or thiourea group.

Claim (Index 17):
A method for providing terminal functionality to a reactive polymer that comprises ethylenic unsaturation, said method comprising:\n a) providing a solution of a hydrocarbon solvent and a carbanionic polymer that comprises ethylenic unsaturation; b) introducing to said solution a cyclic compound defined by the formula where\n each of R 1  and R 2  independently is a hydrogen atom or a substituted or unsubstituted hydrocarbyl group, \n n is an integer of from 3 to 8, inclusive, and\n Z is an O atom, S atom, BR 7  group where R 7  is an O atom, H atom or C 1 -C 12  alkyl group, or NR 3  group where R 3  is a hydrogen atom or a hydrocarbyl group, \n \n thereby providing a reactant polymer; and c) introducing to said solution or introducing said solution to a source of fluoride ions and a stoichiometric excess of silanes that comprise\n (1) at least one silane that comprises at least one primary amine, secondary amine, phosphine, hydroxyl, thiol, cyano, urea or thiourea group and \n (2) at least one silane defined by the formula (R 4 O) 3-a R 4 a SiR 5 SiR 4 a (OR 4 ) 3-a  where each a independently is an integer of from 0 to 2, each R 4  independently is a C 1 -C 12  alkyl group, and R 5  is a C 2 -C 10  alkylene group that optionally comprises a polysulfide linkage, and \n allowing said silanes to react with said reactant polymer, thereby providing said terminal functionality to said polymer.
