纤维素酯是纤维素衍生物，在塑料、薄膜、纤维、涂料、纺织工业等中具有广泛的应用。以醋酸丙酸纤维素（CAP）为例，高粘度CAP产品广泛应用于印刷油墨、热熔浸漆、生漆等领域。然而，由于硫酸作为催化剂的过度使用，可以降解纤维素，从而影响产物的粘度和分子量，因此制备高粘度CAP衍生物一直是并且仍然是一个巨大的挑战。在此，通过使用二乙烯基苯与4-乙烯基苄基氯的共聚物，（PDVB-VBC）为载体，含咪唑的离子液体（IM）为连接剂，聚氧乙烯酸盐（POM）为催化活性中心，制备了新型固体酸催化剂PDVB-VBC-IM-POM，核磁共振仪
Cellulose esters are cellulose derivatives with broad application in plastics, films, fibers, coatings, textiles industries, and so forth. Taking cellulose acetate propionate (CAP) as an example, high-viscosity CAP products are widely used in printing inks, hot-melt dip coatings and lacquer coatings, and so forth. However, it was and remains to be a great challenge to manufacture high-viscosity CAP derivatives because of the overuse of sulfuric acid as catalyst that can degrade cellulose and then affect the viscosity and molecular weight of the product. Herein, with use of the copolymer of divinylbenzene with 4-vinylbenzyl chloride (PDVB–VBC) as support, imidazole-containing ionic liquid (IM) as linker, and polyoxometalates (POMs) as catalytic active sites, novel solid acid catalysts of PDVB–VBC–IM–POMs are prepared and fully characterized by Fourier transform infrared, scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, nuclear magnetic resona...
