【摘要】 采用种子半连续乳液聚合的方法,将一种新型的可聚合离子单体烯丙氧基羟丙基磺酸钠(COPS-1)引入到聚合体系中,制备了稳定的无皂丙烯酸酯乳液。X射线光电子能谱(XPS)分析表明.COPS-1参与乳液共聚后,在乳液的干燥成膜过程中不易向胶层表面迁移富集。与常规的乳液压敏胶相比,该无皂乳液压敏胶具有良好的耐水性和压敏胶粘性能。更多还原

【Abstract】 A stable soap-free emulsion pressure sensitive adhesive (PSA) was synthesized via seeded semi-continuous emulsion polymerization by using a novel polymerizable ionic monomer sodium 1-allyloxy-2-hydroxypropyl sulfonate (COPS-1). The result of X-ray photoelectron spectroscopy shows that after emulsion co-polymerization, the ionic monomer COPS-1 is not easy to migrate to the PSA surface and concentrate there when the emulsion is dried by heating. Compared with conventional emulsion PSA, the soap-free emulsion PSA shows better water resistance and adhesive properties. ,更多还原
