阅读说明：本技术 包含无定形丙烯-乙烯共聚物和丙烯聚合物的粘合剂组合物 (Adhesive compositions comprising amorphous propylene-ethylene copolymers and propylene polymers ) 是由 T.R.卡瓦诺 M.C.屈珀斯 T.H.奎因 于 2018-06-08 设计创作，主要内容包括：在本文中描述了无定形丙烯-乙烯共聚物,其可以包含大量乙烯并表现出合意的软化点与针入度。在这些丙烯-乙烯共聚物中软化点和针入度的合意的组合使它们具有宽操作窗口。由于它们的宽操作窗口,该丙烯-乙烯共聚物可用于多种应用和产品,包括热熔性粘合剂。(Amorphous propylene-ethylene copolymers are described herein that can contain large amounts of ethylene and exhibit desirable softening points and strikethrough. The desirable combination of softening point and penetration in these propylene-ethylene copolymers makes them have a wide operating window. Due to their wide operating window, the propylene-ethylene copolymers are useful in a variety of applications and products, including hot melt adhesives.)
