PROCESS FOR CROSSLINKING THERMOPLASTIC POLYMERS WITH SILANES EMPLOYING PEROXIDE BLENDS, THE RESULTING CROSSLINKED THERMOPLASTIC POLYMER COMPOSITION AND ARTICLES MADE THEREFROM

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.
