A backbone modified polymer comprising the reaction product of an elastomeric polymer and a sulfide modifier represented by Formula 1: AS-Y-Zm (Formula 1), and wherein Y is (C<SUB>12</SUB>-C<SUB>100</SUB>) aralkyl, (C<SUB>12</SUB>-C<SUB>100</SUB>) aryl, (C<SUB>12</SUB>-C<SUB>100</SUB>) alkyl, or (C<SUB>12</SUB>-C<SUB>100</SUB>) dialkylether (alkyl-O-alkyl), and wherein each may be optionally substituted with (C<SUB>1</SUB>-C<SUB>4</SUB>) alkyl, (C<SUB>1</SUB>-C<SUB>4</SUB>) alkoxy, (C<SUB>7</SUB>-C<SUB>16</SUB>) aryl, (C<SUB>7</SUB>-C<SUB>16</SUB>) aralkyl, nitrile, amine, NO<SUB>2</SUB>, alkoxy, or thioalkyl; S is sulfur; A is hydrogen, -(S)<SUB>p</SUB>-R1 or -MR2R3R4; Z is -SH, -S-MR5R6R7, -S-(S)<SUB>p</SUB>-R8, -NR9R10, -NR11COR12, -O-CO-R13, -NCO, or -COOR14; M is silicon or tin; N is nitrogen; O is oxygen; m is the number one, two or three; p is the number one, two, three, four or five; R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13 and R14 are the same or different, and are each, independently, selected from hydrogen (H), (C<SUB>1</SUB>-C<SUB>16</SUB>) alkyl, (C<SUB>6</SUB>-C<SUB>16</SUB>) aryl, (C<SUB>7</SUB>-C<SUB>16</SUB>) aralkyl or (C<SUB>3</SUB>-C<SUB>30</SUB>) tri(hydrocarbyl)silyl, and wherein the hydrocarbyl groups are each independently selected from (C<SUB>1</SUB>-C<SUB>16</SUB>) alkyl, (C<SUB>6</SUB>-C<SUB>16</SUB>) aryl, or (C<SUB>7</SUB>-C<SUB>16</SUB>) aralkyl. The invention also provides related compositions, methods and articles. |
