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.
