Abstract:
A derivative of a silane functionalized interpolymer prepared according to a process comprising contacting one or more addition polymerizable monomers lacking silane functionality and one or more alkenylsilane compounds corresponding to the formula: AnJjSiH4-(n+j) wherein:J is C1-40 hydrocarbyl, A is a C2-20 alkenyl group, n is 1 or 2, and j is 0, 1 or 2; with a catalyst composition comprising a Group 4 metal complex comprising from 1 to 3 &pgr;-bonded anionic or neutral ligand groups, under addition polymerization conditions, wherein the interpolymer comprises from 0.01 to 100 long chain branches per 10,000 carbons, said derivative being formed by one or more subsequent silane conversion processes selected from the group consisting of: a) coupling of one or more chains of such interpolymers, b) hydrolysis, alcoholysis, oxidation, or aminolysis to give Siâ€”OR4 or Siâ€”NR42 groups, where R4 is H or C1-10 hydrocarbyl; c) hydrolysis and neutralization to give ionomers having Siâ€”OR6 groups, where R6 is a metal cation; and d) condensation with an inorganic substrate having surface hydroxyl groups or a polyfunctional linker compound containing two or more alcohol, amine, epoxy, peroxide, carboxy, isocyanate, nitrile, amide, ketone, ester, or diazonium groups or metal salt derivatives of carboxy groups.
