Abstract:
A method for grafting 2-hydroxyethyl methacrylate onto a polyolefin comprising the steps of:a) contemporaneously adding a predetermined amount of the polyolefin, a predetermined amount of 2-hydroxyethyl methacrylate and a predetermined amount of a free radical initiator to a reaction vessel, wherein the polyolefin has a number average molecular weight of greater than about 40,000 g/mol;b) mixing the constituents of (a) under appropriate conditions to melt graft greater than 11 weight percent of 2-hydroxyethyl methacrylate onto the polyolefin at a grafting efficiency greater than 50%; andc) solidifying the melt grafted polyolefin; wherein the melt grafted polyolefin is substantially soluble in xylenes.
