Abstract:
1. A composition comprising a modified polymer comprising: at least one branched modified polymer macromolecule comprising at least one of structures (ib1), (ib2), (ib3), or (ib4); and at least one linear modified polymer macromolecule comprising the structure (iib1); wherein the at least one branched modified polymer macromolecule and the at least one linear modified polymer macromolecule each, independently comprises at least one amine group selected from the group consisting of: and combinations thereof; where N is a nitrogen atom; C is carbon atom; H is a hydrogen atom; E is selected from the group consisting of (i) a (C where R R R R a is the number 2; and b is the number 0; and where (ib1) is a four valent silicon or tin atom selected from the group consisting of (R′″) (ib2) is a group of Formula 2A: (ib3) a group of Formula 2B: (ib4) is a group of Formula 2C: (iib1) is a tertiary amine group of Formula 3A: wherein, Si and Si′ are each silicon atoms; S is a sulfur atom; O is an oxygen atom; R″ is selected from the group consisting of alkyl, aryl and aralkyl; R R R R R R R R q is the number 0 or 1; r is the number 0 or 1; q+r is 0 or 1; s is the number 0 or 1; t is the number 0 or 1; s+t is the number 0 or 1; u is the number 0, 1 or 2; v is the number 0, 1 or 2; u+v is 2; w is the number 0 or 1; x is the number 0 or 1; w+x=1; and the remaining free valences of the four valent silicon atom are each linked to an alpha-modified polymer macromolecule.
