摘　　要：在乳液共聚合的基础上计算了聚马来酸二丁酯(PDBM)的虚拟玻璃化温度,并研究了它在醋丙、苯丙和纯丙乳液体系中的应用。结果表明,聚马来酸二丁酯的玻璃化温度为-15.36℃,该单体在涂料、粘合剂方面可以部分代替丙烯酸丁酯,降低产品的成本。On the basis of emulsion copolymerization, the glass transition temperature （Tg） of dibutyl maleate （DBM） was measured through linear regression, which is about -15.36℃. It indicated that DBM can replace butyl acrylate partly in the emulsion of vinyl acetate - acrylates, styrene - acrylates and acrylates - acrylates systems, which is very important for the cost reduction in the field of coatings, adhesives and relevant products.
