    Abstract: An adhesive composition includes a first acrylic polymer preparable from first components and a second acrylic polymer. The first components comprising i) a branched first alkyl (meth)acrylate having from 4 to 22 carbon atoms, and ii) at least one of acrylic acid and methacrylic acid. The second acrylic polymer is preparable from second components comprising iii) at least one second alkyl (meth)acrylate having from 4 to 22 carbon atoms, iv) a (meth)acrylamide represented by the formula wherein R1 is H or methyl, and R2 and R3 each independently represents H or an alkyl group having from 1 to 8 carbon atoms, or taken together R2 and R3 may form a divalent alkylene group having from 4 to 6 carbon atoms, and v) at least one high Tg macromer having a terminal free-radically polymerizable unsaturated group, the high Tg macromer having a Tg of at least 45° C. Based on the combined total weight of the at least one first acrylic polymer and the at least one second acrylic polymer, the at least one second acrylic polymer is present at a level of from 5 to 40 percent by weight. Methods of making the adhesive composition are also disclosed.

    Abstract: 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.

    Abstract translation: 形成粘合剂组合物的方法包括以下步骤：（a）将包含至少一种自由基（共）可聚合烯属不饱和材料的非脱气混合物与可密封包装组合，其中所述包装含有非脱气混合物; （b）密封包装中的非脱气混合物以形成密封包装; 和（c）将密封包装中的未脱气的混合物暴露于电离辐射源，时间足以引发至少一部分自由基（共）可聚合烯属不饱和材料的（共）聚合 以在密封包装中形成粘合剂组合物。 （共）聚合基本上非绝热地发生。 包装的至少一部分可熔融并与粘合剂组合物混合，以便当将含有粘合剂组合物的密封包装加热至足以熔化至少一部分包装的温度时，提供可流动的可涂覆粘合剂组合物。
