Claim Text:
1. A highly branched polyolefin, comprising: units derived from olefins and at least one multi-functional monomer unit derived from 3,9-divinyl-2,4,8,10-tetraoxaspiro[5,5]undecane; wherein the highly branched polyolefin has: (i) a branching index, g′(vis), of less than about 0.7; (ii) a phase angle, 6, of less than about 55 degrees at a complex modulus of 10 kPa, measured at 190° C.; (iii) a gel content of less than or equal to about 10%; (iv) a melting point of less than about 135° C.; and wherein the highly branched polyolefin is obtained by contacting one or more polyolefins with a free radical generator, a multi-functional monomer, and a modifying polymer dissimilar to the polyolefin.
