丙烯酸甲酯-氰尿酸三烯丙酯共聚物的合成及其孔结构的研究Ⅰ.

STUDY ON THE PREPARATION AND PORE STRUCTURES OF COPOLYMER OF TRIALLYL CYANURATE AND METHYL ACRYLATE

氰尿酸三烯丙酯(TAC)与丙烯酸甲酯(MA)在致孔剂如环己烷、正丁醚或甲苯-汽油(200~#)存在下,用悬浮聚合得到一系列大孔共聚物。对这些共聚物孔结构的研究表明,它们的平均孔径达10000—80000(?),同时研完了致孔剂的分子结构和用量对共聚物孔结构的影响,并初步讨论特大孔共聚物形成的机理。

Copolymer is prepared by the suspension copolymerization of triallyl cyanurate (TAC) and methyl acrylate (MA) in the presence of diluents such as cyclohexane, n-butyl ether, or toluene-gasoline (200#). The pore-structure parameters of the copolymer beads were determined. The study of pore structure shows that average pore radius is 10000-80000 A. The effects of molecular structure and amounts of the diluents on the pore structure of the beads were studied. The mechanism of forming super-macropore was disscused preliminarily.
