摘要:
The invention is directed to an activated halo-containing aralkylsilanes possessing at least one hydrolyzable group bonded to a silicon atom and at least one halo functional group bonded to a carbon atom to which both the silicon atom and an aromatic group are covalently bonded. The invention is also directed to a process for making such a silane as well as its use in rubber compositions and articles containing such rubber compositions, such as tires.

摘要:
Sulfur-containing silanes described herein can serve as coupling agents for fillers in elastomer compositions used, for example, in tires, belts, hoses, shoe soles, seals, gaskets, and the like. The sulfur containing silanes advantageously reduce or eliminate the generation of volatile organic compounds (VOCs) during use.
摘要:
In one embodiment herein there is provided a composition comprising (i) one or more unsaturated silane compounds according to the Formula (1): G1R1SiX1X2 (1) wherein G1 is an olefinically unsaturated hydrocarbon group optionally heteroatom-substituted with one or more oxygen and/or nitrogen atoms; R1 is selected from the group consisting of alkyl, aryl, aralkyl and arenyl; each of X1 and X2 is independently a hydrolyzable group or alternatively each of X1 and X2 is a hydrolyzable group having a direct bond to the silicon atom and also simultaneously a direct bond to each other to form a ring with the silicon atom of the unsaturated silane of Formula (1); and (ii) a system of at least two peroxides comprising a first peroxide having a first 0.1 hour half-life temperature and a second peroxide having a second 0.1 hour half-life temperature, the first and second 0.1 hour half-life temperatures in said composition having a temperature differential of at least about 5° C. In another embodiment herein there is provided a process for producing a silane-grafted thermoplastic polymer. In yet a further embodiment herein there is provided a process for producing a crosslinked thermoplastic polymer. In yet an even further embodiment there is provided an article.
