  • Publication number: 20120091620
    Abstract: A combination of vinyl trimethoxysilane and vinyl triethoxysilane can be grafted onto polyethylene to produce a polyethylene graft terpolymer that can be crosslinked without a significant reduction in crosslinking rates relative to vinyl triemethoxysilane grafted polyethylene. The combination of vinyl trimethoxysilane and vinyl triethoxysilane apparently act synergistically. While byproduct methanol from crosslinking with trimethoxysilane is very undesirable in some products, byproduct ethanol from crosslinking is less hazardous, especially at ppm levels.

  • Publication number: 20120065319
    Abstract: This invention relates to the modification of elastomers by reaction with unsaturated silanes, to the modified elastomers produced and to articles produced by shaping and curing modified elastomer compositions. It also relates to the use of unsaturated silanes as coupling agents in filled elastomer compositions. In a process according to the present invention, the silane has the formula: R?—CH?CH—C(O)X—Y—SiRaR?(3-a) (I) or R?—C?C—C(O)X—Y—SiRaR?(3-a) (II) in which R represents a hydrolysable group; R? represents a hydrocarbyl group having 1 to 6 carbon atoms; a has a value in the range 1 to 3 inclusive; Y represents a divalent organic spacer linkage comprising at least one carbon atom separating the linkage —C(O)X— from the Si atom, X is selected from S or O; and R? represents hydrogen or a group having an electron withdrawing effect with respect to the —CH?CH— or —C?C— bond. This provides silanes able to react efficiently with a diene elastomer in the presence of a free radical initiator.
