    • Continuous or continual in-line processes for forming adhesive polymer blend compositions are described, as well as the application of those blends to a variety of substrates. In one or more embodiments, a first polymer component is provided in a first vessel, and a second polymer component is provided in a second vessel. The first polymer component comprises one or more styrenic block copolymers and one or more hydrocarbon tackifier resins, and the second polymer component comprises a polyolefin. The first and second polymer components are extracted from their respective holding vessels, mixed, and applied to a substrate. In some embodiments, the first and second polymer components may further comprise various additives. Adhesive blend compositions formed from the inventive processes are also described.
    • 描述了用于形成粘合剂聚合物共混物组合物的连续或连续的在线方法,以及将这些共混物应用于各种基材。 在一个或多个实施方案中,在第一容器中提供第一聚合物组分,并且在第二容器中提供第二聚合物组分。 第一聚合物组分包含一种或多种苯乙烯嵌段共聚物和一种或多种烃增粘树脂,第二聚合物组分包括聚烯烃。 第一和第二聚合物组分从其各自的保持容器中提取,混合并施加到基底上。 在一些实施方案中,第一和第二聚合物组分可进一步包含各种添加剂。 还描述了由本发明方法形成的粘合剂共混物组合物。
