    Abstract: The present invention includes a multicomponent structure comprising at least two components having a tie layer or adhesive layer directly between them, the tie layer comprising at least one olefin unsaturated ester copolymer and at least one photoinitiator and optionally a crosslinking enhancer. The tie layer is preferably irradiated with sufficient actinic radiation to result in increased interlayer adhesion strength between the two components as compared with the interlayer adhesion strength before treatment with the actinic radiation or between the components having a tie layer of the same composition except without the added photoinitiator or crosslinking enhancer. Without the photoinitiator, optionally crosslinking enhancer, and radiation the interlayer adhesion of the components is preferably less than 55 N/m. At least one of the components (first component or layer) preferably comprises a halopolymer, more preferably vinylidene chloride polymer, most preferably at least a majority of a vinyl idene chloride polymer. In another embodiment, at least one component exhibits interlayer adhesion strength similar to vinylidene chloride polymers. The structure optionally is or comprises such structures as a multilayer film, bag, or package, a lined or composite pipe, or other structure having more than one component. The tie layer is advantageously irradiated with an amount of UV light effective to increase the adhesion strength between the first and second components.

    Abstract translation: 本发明包括多组分结构,其包含至少两个在其间直接连接层或粘合剂层的组分,所述粘结层包含至少一种烯烃不饱和酯共聚物和至少一种光引发剂和任选的交联增强剂。 与使用光化辐射处理之前的层间粘合强度或具有相同组成的粘结层的组分之间相比,接合层优选用足够的光化辐射照射以导致两组分之间的层间粘合强度增加,除了不添加 光引发剂或交联增强剂。 没有光引发剂,任选的交联增强剂和辐射,组分的层间粘附优选小于55N / m。 组分(第一组分或第一层)中的至少一种优选包含卤代聚合物,更优选偏二氯乙烯聚合物,最优选氯乙烯基氯化聚合物的至少大部分。 在另一个实施方案中,至少一种组分显示类似于偏二氯乙烯聚合物的层间粘合强度。 该结构任选地或包括诸如多层膜,袋或包装,衬里或复合管或具有多于一种组分的其它结构的结构。 接合层有利地用一定量的UV光照射,以有效地增加第一和第二组分之间的粘合强度。
