摘要:
For providing biocides such as 10,10'-oxybisphenoxarsive (OBPA) in concentrated, immobilized form to an end use resin composition containing a primary thermoplastic resin with which the primary resin is incompatible at high concentrations, solid biocide resin concentrates are provided which immobilize high concentrations of biocide. The solid biocide resin concentrates may contain an alloy of two thermoplastic resins, one of which is substantially identical to the primary resin and one of which enables incorporation and immobilization of high concentrates of biocide in the solid biocide resin concentrates. The solid biocide resin concentrate may contain, in whole or in part, a thermoplastic copolymer having mer units such as are present in the primary resin in addition to dissimilar mer units which enhance compatibility of the biocide with the copolymer.

摘要:
Solutions of microbiocides in cosolvents having alkanol moieties and concentrate compositions of carriers, microbiocides and cosolvents having alkanol moieties are stabilized against UV-catalyzed oxidation by the addition of phenolic antioxidants. The solutions or concentrate compositions are added to polymeric resins and formed, e.g., by fusion, into polymer compositions exhibiting microbiocidal properties.
摘要:
Solid solutions comprise a water-soluble thermoplastic resin and a microbicide dissolved therein. These solutions may be added to a rigid thermoplastic resin composition to impart biocidal characteristics thereto. If the microbicide is water-insoluble, the solid solutions may be used to prepare stable dispersions of the microbicide. The solutions also provide for slow release of a microbicide or as a vehicle for providing microbicide to an aqueous solution.

摘要:
A composition comprising a dry blend mixture of a porous thermoplastic resin powder and from 1 to 80 wt. % of a microbiocide based upon the weight of the. composition. The microbiocide is present in the mixture at a concentration of at least about 20 times greater than the normal upper usage concentration of the microbiocide, and is held within the pores of the thermoplastic powder. The resulting concentrate is a substantially non-dusting, free-flowing powder which is readily incorporated into a second thermoplastic resin to produce a resulting article having the appropriate level of microbiocide.
