ANTIMICROBIAL POLYMER MATERIALS Russian patent published in 2005 - IPC

FIELD: polymer materials.

SUBSTANCE: invention relates to process of preparing antimicrobial polymer material that can be used in medicine, food processing and light industries, in agriculture, and in domestic sphere to manufacture textile materials, nonfouling film, and a variety domestic articles (disposable ware, bottles, glasses, and the like) wherein antimicrobial properties are desirable, fungi-resistant rubber, acrylate-based disinfecting flocculants, hygienic facilities, and so on. Material consists of 0.1-2.0% polyguanidine compound, 0.1-2.0% dimethyl-bis(4-phenylaminophenoxy)silane, 0.05-2.0% organic acid, and polymer component (the balance). Polyguanidine compound is selected from polyhexamethyleneguanidine chloride, phosphate, citrate, lactate, sorbate, and benzoate; poly(4,9-dioxadodecanguanidine) phosphate, polyhexamethylenebiguanide chloride, and polyhexamethylenebiguanide phosphate. Organic acid utilized can be citric, lactic, succinic, or benzoic acid. Polymer compound can selected from high- or low-density polyethylene or polypropylene, or their mixture, copolymers of ethylene with propylene or higher olefins, shock-resistant polystyrene, polyacrylic acid, polyamide, polyethylene terephthalate, polypeptide, cellulose, cellulose, polyvinylchloride, vinylene dichloride copolymers, butadiene/styrene copolymer, polyacrylonitrile, and hydrolyzed polyacrylamide. Material additionally contains a dye.

EFFECT: simplified polymer material manufacture technology, increased protective, antibacterial, antioxidant, antimoldy, algaecide, and antiyeast activities.
