摘要： A heat-recoverable closure with a crosslinked pressure-sensitive adhesive is provided. The closure member is comprised of a heat-recoverable sheet and a layer of crosslinked pressure-sensitive adhesive, which maintains the closure of the closure member having the recovery process. The combination of a high surface energy heat-recoverable sheet and the crosslinked pressure-sensitive adhesive yield an article having excellent performance as a closure member.

摘要： A crosslinked pressure-sensitive high shear adhesive is provided which is comprised of:(a) an acrylate terpolymer comprised of(i) at least one alkyl acrylate wherein the alkyl group has at least 5 carbon atoms and wherein a major portion of the alkyls have an alkyl group having from 5 to 12 carbon atoms;(ii) a second alkyl acrylate wherein the alkyl group has from 1 to 4 carbon atoms;(iii) at least one copolymerizable monoethylenically monomer selected from the group consisting of acrylic acid, methacrylic acid and itaconic acid; and(b) an amine formaldehyde condensate, in an amount of from about 0.8 to 10 percent by weight of the terpolymer.The pressure sensitive adhesive is particularly useful when it is combined with a reinforcing web and a reinforcing filler and applied to a carrier to form an adhesive tape. The adhesive is particularly useful in adhering the edges of a heat-recoverable sheet to one another to secure the closure during the closure process.A chromophore-substituted trihalomethyltriazine is preferably used as an additional crosslinking agent.
摘要翻译： 提供交联压敏高剪切粘合剂，其包含：（a）丙烯酸酯三元共聚物，其包含（i）至少一种丙烯酸烷基酯，其中烷基具有至少5个碳原子，并且其中主要部分的烷基具有 具有5至12个碳原子的烷基; （ii）第二烷基丙烯酸酯，其中所述烷基具有1至4个碳原子; （iii）至少一种选自丙烯酸，甲基丙烯酸和衣康酸的可共聚单烯属单体; 和（b）胺甲醛缩合物，其量为三元共聚物重量的约0.8-10％。 当压敏粘合剂与增强网和增强填料结合并施加到载体以形成粘合带时，压敏粘合剂是特别有用的。 粘合剂特别可用于将热可回收片材的边缘彼此粘合以在封闭过程中固定封闭物。 发色团取代的三卤代甲基三嗪优选用作另外的交联剂。
