Antibacterial macromolecule polymer and preparation method thereof

The invention discloses high molecular polymer having antibacterial performance and the preparation method thereof. The polymer is copolymer generated by polymerizing at least a vinyl halogenated phenol monomer A and at least a vinyl pyridine monomer B; the copolymer is random copolymer, block copolymer, or branched copolymer. Because the molecular structure includes a halogenated phenol base group and a tertiary amine base group which are mutually linked to generate quarternary ammonium salt, thereby having good antibacterial performance, and the problem of ineffective bacterial resistance caused by the drain of small molecule of the prior quarternary ammonium salt functional group antibacterial high molecule is solved; the polymer of the invention has the advantages of long efficiency, no small molecule leakage, no pollution, antibiosis universality, etc.; the invention can be widely used for the fields of food package, medical appliances, public equipment, sewage treatment, clothes,coating material, household electric appliances, biomaterial, etc.
