Patent ID: 7351774

Claim:
An organosilicon composition containing from about 0.1% to about 10% by weight bound silicon present as C—Si bonds, wherein a carbon to silicon covalent bond was created by a reaction between an unsaturation in a crumb rubber particle and a silicon hydride having the formula: R x Si y H z wherein R is selected from the group consisting of (a) monovalent hydrocarbon radicals or substituted hydrocarbon radicals from C1 to C20, including hydrocarbon radicals and substituents such as alkyl radicals, straight chain or branched, C3 to C6 cycloalkyl radicals, aryl radicals, and alkaryl radicals; (b) halogen atoms; (c) alkoxy radicals; (d) carboxy radicals; and (e) ester radicals; and wherein z has a value of 1 to 3; x has a value of 0 to 3; and y ranges from 1 to 10; and further, if x is greater than 1, the R moieties may be the same or different; and the reaction occurs with no added catalyst.
