Composition for imparting anti-bacterial characteristics to vinyl resins
Abstract
Abstract VINYL RESINS WHILE INERT TO MICROBIAL AND FUNGAL ATTACK, CAN ACT AS CARRIERS FOR MICROORGANISMS AND PHENOXARSINE COMPOUNDS ARE USED TO IMPART MICROBICIDAL PROPERTIES TO SUCH RESINS. THE AMOUNT OF PHENOXARSINE COMPOUNDS REQUIRED TO IMPART SUCH MICROBICIDAL PROPERTIES TO VINYL RESIN MATERIALS MAY BE MARKEDLY REDUCED WHEN THE PHENOXARSINE COMPOUNDS ARE USED IN CONJUNCTION WITH HEXACHLORODIMETHYL SULFONE WHICH ACTS TO PROMOTE THE EFFECTIVENESS OF THE PHENOXARSINE COMPOUNDS EVEN THOUGH THE SULFONE PER SE IMPARTS NO MICROBICIDAL PROPERTIES TO A VINYL MATERIAL. IN A PREFERRED EMBODIMENT OF THE INVENTION, HEXACHLORODIMETHYL SULFONE IS INCORPORATED INTO THE NONYL PHENOL SOLUTION OF, FOR EXAMPLE, 10,10'' OXYBISPHENOXARSINE AND THE PHENOL SOLUTION INCORPORATED INTO VINYL RESIN PLASTICIZERS, SUCH AS EPOXIDIZED SOYA, SO THAT THE PHENOXARSINE AND SULFONE SOLUTE COMPONENTS WILL BE PRESENT IN THE RESIN IN AMOUNTS OF 50 TO 250 PARTS PER MILLION OF PHENOXARSINE COMPOUND AND 100 TO 1000 PARTS PER MILLION OF SULFONE COMPOUND.
