摘要： A method for forming a polylactide film includes the steps (a) through (c). In step (a), a treated tool surface is provided with a release coating. The treated tool surface is maintained at a predetermined temperature of about the glass transition temperature of the polylactide or higher. In step (b) the treated tool surface is contacted with a molten polylactide composition to provide a polylactide film. The film is at least partially crystalline, and the crystallinity of the polylactide film is enhanced due to exposure of the molten polylactide composition to the treated tool surface at the predetermined temperature. In step (c) the polylactide film is removed from the treated tool surface. Additionally, a film is provided that is made by the foregoing method, and the film may be formed into an article or a part of an article. In some cases, the article is a disposable garment such as a diaper. In other cases, the article may be a tape made with the foregoing film, where the film includes first and second major surfaces and a layer of adhesive on at least one of the major surfaces.

摘要： Methods of (co)polymerizing ethylenically-unsaturated materials, including the steps of providing a mixture of free radically (co)polymerizable ethylenically-unsaturated material in a mold, exposing the mixture in the mold to a source of ionizing radiation for a time sufficient to initiate (co)polymerization of at least a portion of the free radically (co)polymerizable ethylenically-unsaturated material, and allowing the free radically (co)polymerizable ethylenically-unsaturated material to (co)polymerize in the mold while continuing to expose the mixture to the source of ionizing radiation for a time sufficient to yield an at least partially (co)polymerized (co)polymer. The ethylenically-unsaturated materials are selected from vinyl-functional monomers, vinyl-functional oligomers, vinyl-functional macromers, and combinations thereof. The mixture is preferably free of thermally-induced or UV-induced free radical polymerization initiators. The source of ionizing radiation may be a gamma ray source, an x-ray source, an electron beam source with an emission energy greater than 300 keV, and combinations thereof.

摘要： Ionizing radiation crosslinkable pressure sensitive adhesive precursors containing hydrocarbon tackifiers and having an acid content of no more than 3% by weight. The precursors can be exposed to a source of ionizing radiation, for example, one or both of an electron beam or gamma radiation, for an exposure time sufficient to receive an energy dose sufficient to at least partially crosslink the adhesive precursor, thereby forming a pressure sensitive adhesive. Methods of using ionizing radiation to crosslink a crosslinkable pressure sensitive adhesive precursor are also disclosed.

摘要： Methods of forming an adhesive composition including the steps of (a) combining a non-deaerated mixture comprising at least one free radically (co)polymerizable ethylenically-unsaturated material with a sealable packaging, wherein the packaging contains the non-deaerated mixture; (b) sealing the non-deaerated mixture in the packaging to form a sealed packaging; and (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. The (co)polymerization takes place essentially non-adiabatically. At least a portion of the packaging is meltable and mixable with the adhesive composition so as to provide a flowable 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.
