A conjugated diolefin reacted in is a hydrocar­ bon solvent in the presence of an initiator to form a polymer. After forming the polymer, alkoxy silane ter­ minal functionalizing groups are bonded to the poly­ mer. A stabilizing agent having the formula (R)4- „Si(OH)n wherein R is a Ci to Cis alkyl, Ci to Cis alkyl group containing heteroatom such a as nitrogen or oxy­ gen, C 4 to C cycloalkyl, 8 or C 6 to Cis aromatic group is then added to the polymer, optionally in the presence of hydrocarbon oil. The polymer is then desolvatizing, resulting in a polymer with stable Mooney viscosity and molecular weight, even over prolonged periods of time. Compositions and articles containing the polymer are also described. (81) Designated States (unless otherwise indicated, for every kind of national protection available)'.
