Silica treating of functionalized resins in tires

A process for the preparation of a silica-treated functionalized resin composition comprising the steps of:

• (A) reacting a polymer backbone with a hydrosilylation agent to produce a silane-functionalized resin composition,
• wherein the polymer backbone is selected from at least one of dicyclopentadiene (DCPD)-based polymer, a cyclopentadiene (CPD)-based polymer, a DCPD-styrene copolymer, a C5 copolymer resin, a C5-styrene copolymer resin, a terpene copolymer resin, a pinene copolymer resin, a C9 copolymer resin, a C5/C9 copolymer resin, an alpha-methylstyrene copolymer resin, and combinations thereof;
• wherein the polymer backbone comprises:
• within the range from 60 to 100 wt % cyclic components;
• (i) less than or equal to 15 wt % components derived from piperylene;
• (ii) from 0.1 to 10 wt % components derived from amylene;
• (iii) less than or equal to 15 wt % components derived from isoprene;
• (iv) from 0.1 to 20 wt % components derived from styrene;
• and
• (v) from 5 to 15 wt % components derived from indene;
• and
• (B) mixing the silane-functionalized resin composition with silica to produce a silica-treated functionalized resin composition;
• wherein the hydrosilylation agent is selected from at least one of those represented by formulas (I), (II), or (III):
• where “a” is an integer from 1 to about 1000, and R″ is an alkyl or an aryl group;
• where x is from about 2 to about 40 SiO-groups/moieties, and R is an alkyl or an aryl group;
• where Y is independently a nitrogen, oxygen, or sulfur atom, Z is independently a boron, nitrogen, oxygen, silicon or sulfur atom, R1 is independently a hydrogen atom, or a substituted or unsubstituted alkyl or aromatic group of from 1 to 20 carbon atoms, R2 is independently a divalent substituted or unsubstituted alkyl or aromatic group of from 1 to 20 carbon atoms, R3 is independently a hydrogen atom, a halogen atom, a sulfonate group, a substituted or unsubstituted alkyl or aromatic group of from 1 to 20 carbon atoms, R1, R2, and R3 may form single or multinuclear rings with each other, a-f are independently integers of 1, 2, or 3, with the proviso that a+b+c and d+e+f are both equal to 3, and independently for each Y and Z, if Z is a boron atom, then x=2, if Y or Z is a nitrogen atom, then x=2, if Y or Z is an oxygen atom or sulfur atom, then x=1, if Z is a silicon atom, then x=3.
