Abstract:
1. A process for preparing a functionalised polyolefin, comprising reacting: (i) a polyolefin, (ii) a compound containing a functional group, and (iii) a coagent compound having Formula I: wherein: Y is a core moiety; Z is a moiety containing a carbon-carbon double bond or a carbon-carbon triple bond; X is a moiety different than Z and the bond between X and Y may be a single bond or a double bond; n is a whole number greater than or equal to 0, with the provisos that: (i) when n is 0, Y is an organic moiety, and (ii) when n is a whole number greater than 0, Y is an inorganic moiety; m is a whole number greater than 2; and m+n equals a number up to the valence of Y; the coagent compound being selected from the group consisting of a polyallyl compound, a polyvinyl compound and mixtures thereof; wherein: (a) the coagent compound is initially reacted with one of the compound containing a functional group and the polyolefin to form a product that is then reacted with the other of the compound containing a functional group and the polyolefm; and (b) the compound containing a functional group is substantially inert in free radical-mediated polymerization reactions and in free radical-mediated grafting reactions.
