| titleOfInvention | Method Of Making Diarlysilanediol Containing Polymers, Polymer Compositions And Articles Containing Such Polymers |
| abstract | A method of making a polymer with stable Mooney viscosity and molecular weight is described. A conjugated diolefin is reacted in a hydrocarbon solvent in the presence of an initiator to form a polymer. After forming the polymer, alkoxy silane terminal functionalizing groups are bonded to the polymer. A mixture of at least one of a first stabilizing agent having the formula (R) 4-n Si(OH) n wherein R is a C 1 to C 18 alkyl, C 1 to C 18 alkyl group containing a heteroatom such as nitrogen or oxygen, C 4 to C 8 cycloalkyl, or C 6 to C 18 aromatic group, and a at least one of a second stabilizing agents having the formula (R) 2 Si(OH) 2 wherein R is an aryl group, is then added to the polymer, optionally in the presence of hydrocarbon oil. The polymer is then desolvatized, 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. |
