Claim:
1. A method of forming an adhesive composition comprising the steps of: (a) combining: (b) sealing the non-deaerated mixture in the packaging to form a sealed packaging; (c) exposing the non-deaerated mixture in the sealed packaging to a source of ionizing radiation for a time sufficient to initiate (co)polymerization of at least a portion of the at least one free radically (co)polymerizable ethylenically-unsaturated material to form an adhesive composition in the sealed packaging, wherein the source of ionizing radiation is selected from a gamma ray source, an x-ray source, an electron beam source having an emission energy of greater than 300 keV, and combinations thereof, additionally wherein the polymerization takes place essentially non-adiabatically, further wherein at least a portion of the packaging is meltable and mixable with the adhesive composition so as to provide a coatable adhesive composition when the sealed packaging containing the adhesive composition is heated to a temperature sufficient to melt at least a portion of the packaging.
