摘要
采用水相悬浮浸渍法制备可发泡偏氯乙烯 (VDC) -丙烯腈(AN) -苯乙烯 (St)三元共聚树脂颗粒 ,研究了体系中 1-一氟 - 1,1′-二氯乙烷 (R141b)蒸汽压对R141b分别在水和树脂中溶解量的影响 ,并进行了发泡剂加入量的设计。
Expandable vinylidene chloride (VDC)-acrylonitrile(AN)-styene(St) terpolymer particles were prepared with monofluorodichloroethane(R141b)as blowing agent in water. The relationship between the solubilities of JR141b in water and VDC copolymer resin and R141b vapour pressure were studied. The results were used to design the theoretical addition of R141b.
