ABSTRACT:
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.
