ISOBUTYLENE-BASED CATIONIC SALT POLYMER, PREPARATION METHOD THEREFOR, USE THEREOF, AND ANTIBACTERIAL POLYMER MATERIAL

The present invention relates to the field of polymer materials. Disclosed are an isobutylene-based cationic salt ionic polymer, a preparation method therefor, and the use thereof. The polymer comprises a structure represented by formula (2) and/or formula (3), and optionally, a structural unit A represented by formula (1), a structural unit B represented by formula (4) and a structural unit C represented by formula (5), Q being formula (6), formula (7), formula (8) or formula (9). The side group and the main chain of the polymer both contain cationic salt groups, so that the polymer has a high polyionic degree and thus can be used as an antibacterial agent for preparing antibacterial polymer materials, such as antibacterial plastics, antibacterial rubber, antibacterial fibers and antibacterial coatings. La présente invention appartient au domaine des matériaux polymères. Sont divulgués un polymère ionique de sel cationique à base d'isobutylène, son procédé de préparation et son utilisation. Le polymère compr
