Polycyclic unsaturated compound, preparation method thereof, stain-resistant opacifying polymer emulsion and preparation method of stain-resistant opacifying polymer emulsion

The invention discloses a polycyclic unsaturated compound and a preparation method thereof, and a stain-resistant opacity polymer emulsion and a preparation method thereof. The structure of the polycyclic unsaturated compound is shown as a formula 1, a polycyclic unsaturated monomer is prepared through a reaction of beta-(acryloyloxy) propionic acid and camptothecin, and when the polycyclic unsaturated monomer is applied to emulsion polymerization, the emulsion covering effect can be remarkably improved, and meanwhile the excellent stain-resistant effect is achieved. The coating prepared by adopting the emulsion has excellent covering effect and stain-resistant effect, and is mainly applied to the field of coating adhesives. 本发明公开了一种多环不饱和化合物及制备方法和一种耐污渍的遮盖聚合物乳液及其制备方法。多环不饱和化合物，结构如式1所示：通过β-(丙烯酰氧)丙酸与喜树碱反应制备多环基不饱和单体，将其应用于乳液聚合中，能够在显著提升乳液遮盖效果的同时兼具优异耐污渍效果。采用该乳液配制的涂料具有优异的遮盖效果和耐污渍效果，主要应用于涂料粘合剂领域。
