Novel polymers having a linear backbone which is free from both branching and cross-linking, comprising quaternized nitrogen atoms linked to each other through trimethylene groups. By the term "linear backbone" is meant that the polymer has only acyclic groups, i. e. trimethylene, linking the nitrogen atoms in a single continuous chain; the polymer is free from "branching" when it has no repeating monomer units extending from the polymer backbone; and it is free from "cross-linking" when there is no joining of two linear backbones. These polymers are useful as antimicrobials, flocculating agents, antistatic agents, electroconductive agents for coating paper, chelating agents and bile acid binding agents, as well as in similar applications where their high charge to weight ratio and fully accessible nitrogen atoms can be employed. The polymers are obtained by the polymerization of dihydro-oxazine, reductive alkylation of the resulting polymer, followed by quaternization.
具有线性骨架的新型聚合物,其不具有分支和交联,包括通过三亚甲基基团相互连接的季
铵氮原子。所谓“线性骨架”是指聚合物仅具有无环基团,即三亚甲基,将氮原子在单一连续链中连接起来;当聚合物没有从聚合物骨架延伸的重复单体单元时,它是不具有“分支”的;当没有连接两个线性骨架时,它是不具有“交联”的。这些聚合物可用作抗微
生物、絮凝剂、
抗静电剂、用于涂覆纸张的导电剂、
螯合剂和
胆酸结合剂,以及在类似应用中,它们的高电荷重比和完全可访问的氮原子可以被利用。该聚合物是通过二氢
噁唑的聚合、得到的聚合物的还原烷基化,随后进行季
铵化而获得的。
