alpha -alkylacrylate functionality is added to an olefinically unsaturated polymer by reacting with a novel grafting agent in the presence of a hydrosilation catalyst to produce a polymer with at least one alpha -alkylacrylate group attached pendently thereto. The grafting agent is a compound of structure (A) or (B) or a mixture thereof:
<CHEM>
Where R<1> is an alkyl group: R<2>; is a divalent group nonreactive under hydrosilation reaction conditions; n is o, 1,2,3, or 4; x and y are each 0,1,2,3 or 4 and x+y= 1,2,3, or 4; and the R<3> groups, which may be the same or different each represent alkyl, substituted alkyl, aryl, substituted aryl, or
<CHEM>
in which R<1> and R<2> are as defined above. |
