Abstract 1. A POLYMERIZATION PROCESS WHICH COMPRISES POLYMERIZING MONOMERS SELECTED FROM THE GROUP CONSISTING OF CONJUGATED DIENES AND CONJUGATED DIENES IN ADMIXTURE WITH VINYL-SUBSTITUTED AROMATIC COMPOUNDS, WITH AN ALKALI METAL, ORGANOALKALI METAL, OR ORGANOALKALINE EARTH METAL INITIATOR, THEREBY PRODUCING POLYMER CONTAINING TERMINAL REACTIVE ALKALI OR ALKALINE EARTH METAL GROUPS, WHEREIN THE IMPROVEMENT COMPRISES MODIFYING SIAD POLYMER TO INCREASE THE FILLER-POLYMER INTERACTION IN FILLER-LOADED STOCKS BY TREATING SAID POLYMER CONTAINING TERMINAL REACTIVE ALKALI OR ALKALONE EARTH METAL GROUPS WITH A MODIFYING AGENT CONSISTING ESSENTIALLY OF AT LEAST ONE R(Z-1)MX WHEREIN R IS A HYDROCARBON RADICAL CONTAINING UP TO 12 CARBON ATOMS, M IS A METAL SELECTED FROM GROUPS 2B, 4A, AND 5A, X IS A RADICAL SELECTED FROM THE GROUP CONSISTING OF HALOGEN, -OR, -SR, AND -N(R)2 AND Z IS AN INTEGER EQUAL TO THE VALANCE OF M.
