Patent number: 8569417Abstract: The invention relates to a process for grafting hydrolysable silane groups to a polyolefin in which ethylene units, if present, form less than 50% by weight of the total polyolefin. The polyolefin is reacted with an unsaturated silane, having at least one hydrolysable group bonded to Si, or a hydrolysate thereof, in the presence of means capable of generating free radical sites in the polyolefin. The unsaturated silane has the formula R?—CH?CH—Z (I) or R?—C?C—Z (II) in which Z represents an electron-withdrawing moiety substituted by a —SiRaR?(3-a) group wherein 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; and R? represents hydrogen or a group having an electron withdrawing or any other activation effect with respect to the —CH?CH— or —C?C— bond.Type: GrantFiled: July 2, 2009Date of Patent: October 29, 2013Assignee: Dow Corning CorporationInventors: Michael Backer, Francois De Buyl, Valerie Smits, Damien Deheunynck
