Cationic ring-opening polymerizations of [3.3.1] propellane derivatives, 1, 3-dehydroadamantane (1), 5-butyl-1, 3-dehydroadamantane (2), and 6-butyl-6-methyl-1, 3-dehydroadamantane (3) were carried out with CF_3SO_3H in CH_2 Cl_2 at 0℃ for 6-42 h. The central a-bonds in 1-3 were exclusively opened to afford novel poly ([3.3.1]propellane)s, poly(1, 3-adamantane)s, in good to quantitative yields. The resulting poly (2) and poly (3) possessing flexible butyl substituents were soluble in chloroform, THF, and 1, 2-dichlorobenzene, and the degree of polymerization was estimated to be greater than 30, while the poly (1) was hardly soluble in the common organic solvents. All aliphatic poly (1, 3-adamantane) s showed high thermal stability, whose 10% weight loss temperatures were over 430℃. 1, 3-Dehydroadamantanes underwent the spontaneous copolymerization with acrylonitrile or methyl acrylate to afford the alternating copolymer, indicating the high electron-density.

[3.3.1]丙烷衍生物、1, 3-脱氢金刚烷(1)、5-丁基-1, 3-脱氢金刚烷(2)和6-丁基-6-甲基-1, 3-脱氢金刚烷(3)在CH_2 Cl_2中于0℃下用CF_3SO_3H进行阳离子开环聚合反应6-42 h。 1-3中的中心α键被专门打开以提供新型聚([3.3.1]丙烷)、聚(1, 3-金刚烷)，且收率良好至定量。所得具有柔性丁基取代基的聚(2)和聚(3)可溶于氯仿、THF和1,2-二氯苯，聚合度估计大于30，而聚(1)几乎不溶于普通有机溶剂。所有脂肪族聚(1, 3-金刚烷)均表现出较高的热稳定性，其10%失重温度均超过430℃。 1, 3-脱氢金刚烷与丙烯腈或丙烯酸甲酯发生自发共聚，形成交替共聚物，显示出高电子密度。
