The present invention provides a process for producing a durable, external surfactant free, cationic, water based jet ink polymer which when formulated into an ink, coating or film that results in a excellent adhesion to metal or plastic substrates. The hybridized copolymer comprises a hydrophobic functional polymeric backbone comprising a functional vinylchloride-containing polymer portion having an average molecular weight of from 15,000 to 200,000 g/mole and at least one polymer portion selected from the group consisting of a functional polyolefin and a functional polysiloxane. The hybridized copolymer also comprises a plurality of copolymeric side chains attached to the backbone, comprising a polymerizable amine-containing unsaturated monomer, and a polymerizable unsaturated monomer.
本发明提供了一种生产耐久的、不含外表面活性剂的阳离子水基喷墨聚合物的工艺,这种聚合物在配制成墨水、涂层或薄膜时,能与金属或塑料基材产生极佳的粘附性。杂化共聚物包括疏水性功能聚合物骨架,该骨架由平均分子量为 15,000 至 200,000 克/摩尔的含功能性氯乙烯聚合物部分和至少一种选自功能性聚烯烃和功能性聚硅氧烷的聚合物部分组成。杂化共聚物还包括连接到骨架上的多个共聚侧链,包括可聚合的含胺不饱和单体和可聚合的不饱和单体。
