Grafted polyolefin compositions

A modified polyolefin composition comprising from about 70 weight percent to 90 weight percent of a polyolefin homopolymer and from greater than 10 weight percent to about 30 weight percent of 2-hydroxyethyl methacrylate grafted to said polyolefin homopolymer, wherein said modified polyolefin composition is made by the process of

• a) contemporaneously adding to an extruder an amount of the polyolefin homopolymer, an amount of 2-hydroxyethyl methacrylate and an amount of a free radical initiator to a reaction vessel, wherein the amount of the 2-hydroxyethyl methacrylate relative to the amount of polyolefin homopolymer is a ratio of 0.1 to about 0.2 and the amount of free radical initiator relative to the amount of 2-hydroxyethyl methacrylate is a ratio from about 0.025 to about 0.1, wherein said amounts base based on weight, further wherein the polyolefin has a number average molecular weight of greater than about 40,000 g/mol;
• and
• b) mixing the constituents of (a) under appropriate conditions to melt graft 2-hydroxyethyl methacrylate onto the polyolefin at a grafting efficiency of at least 50 percent;
• wherein the modified polyolefin composition is substantially soluble in xylenes, and wherein the modified polyolefin composition is capable of being used in thermoplastic film-forming applications.
