摘　　要：用乳液聚合的方法 ,制备出了具有核壳结构的水性聚氨酯与丙烯酸酯共聚乳液 (PUA乳液 ) ,对PUA的性能进行了初步的研究。结果表明 ,丙烯酸酯的用量对吸水率。Aqueous polyurethane acrylic copolymer emulsion (PUA) with core shell structure has been prepared by emulsion copolymerization. The thermal and mechanical properties of PUA have been studied. The results show that the amount of acrylic has important effects on hygroscopicity, thermal and mechanical properties of emulsion cast film.
