Zusammenfassung:	PROCESS FOR THE PREPARATION OF A RUBBER HAVING POLYMER BOUND FUNCTIONALITY The present invention relates to a process for preparing a rubber containing polymer bound functionalities. The process comprises the emulsion polymerization at a temperature ranging from about 0.degree.C to about 25.degree.C of (a) at least one functionalized monomer that contains a polymerizable vinyl group; with (b) at least one copolymerizable conjugated diene monomer selected from the group consisting of butadiene-1,3, 2-chlorobutadiene-1,3, isoprene, piperylene and conjugated hexadienes; wherein the polymerization is conducted in the presence of from about 1 to about 70 parts by weight of a plasticizer based on 100 parts by weight of total monomers. The plasticizer functions as a cosolvent/dispersing agent for the functionalized monomer during the emulsion polymerization and as a plasticizer for the final polymer product.
