Abstract
This invention discloses a process for the synthesis of a rubbery polymer by emulsion polymerization that comprised polymerizing (1) a conjugated diolefin monomer and (2) a functionalized monomer having the structural formula: wherein the Rgroups can be the same or different and represent hydrogen atoms or alkyl groups containing from 1 to about 8 carbon atoms, wherein Rrepresents a hydrogen atom or an alkyl group containing from 1 to about 8 carbon atoms, wherein Rrepresents a hydrogen atom or an alkyl group containing from 1 to about 8 carbon atoms, and wherein Rrepresents a hydrogen atom or an alkyl group containing from 1 to about 8 carbon atoms, with the proviso that if Rrepresent an alkyl group then Rrepresents a hydrogen atom, and with the proviso that Rrepresents an alkyl group then Rrepresents a hydrogen atom, wherein said polymerization is conducted in an aqueous medium, and wherein said polymerization is initiated with a free radical initiator.
