三烯丙基异氰尿酸酯-醋酸乙烯酯交联聚合物研究(Ⅲ)——致孔剂对共聚物结构的影响

Studies on Crosslink Copolymer of Vinyl Acetate and Triallyl Isocyanurate (Ⅲ) ——Effect of Porogenic Agent on the Structures of the Copolymer

醋酸乙烯酯与异氰尿酸三烯丙酯在不同致孔剂如正辛烷、正庚烷、十氢化萘或醋酸丁酯存在下,用悬浮聚合法得到一系列大孔共聚物,测定和比较了这些共聚物的孔结构。实验结果表明:致孔剂的分子结构和用量对共聚物孔结构有显著的影响,其平均孔径最大可达5000,并初步讨论了致孔机理。

The copolymer was prepared by the suspension copolymerization of vinyl acetate and triallyl isocyanurate in the presence of poregenic agents such as n-octane, n-heptane, decahydronaphthalene or n-butyl acetate. The pore-structure parameters of the copolymer beads were determined.
