1. A resin, comprising:
up to 99.99 weight percent (wt. %) of a first polyolefin grafted with a functional group selected from the group consisting of an ethylenically unsaturated carboxylic acid, a carboxylic acid anhydride, an ester functional group and a combination thereof; and
0.01 to 3.0 wt. % of a tin oxide-based catalyst selected from the group consisting of dibutyltin oxide, dioctyltin oxide and combinations thereof, wherein the resin includes 0.2 wt. % to 1.5 wt. % of the functional group from the first polyolefin, wherein the wt. % is based on a total weight of the resin, wherein a weight percentage ratio of the functional group of the first polyolefin to the tin oxide-based catalyst is from 0.25:1 to 5:1.
