Abstract
Abstract Biocidal compositions useful in controlling the growth of bacteria and fungi in aqueous surface-coating compositions are aqueous solutions that contain from 20 percent to 80 percent by weight of a monocyclic polyoxymethyleneoxazolidine having the structural formula ##EQU1## wherein R represents hydrogen, alkyl of 1 to 6 carbon atoms, phenyl, halophenyl, or --(CH 2 O) m CH 2 OH; each R' represents alkyl of 1 to 6 carbon atoms or --CH 2 OH; m represents a number in the range of 0 to 2; and n represents a number in the range of 1 to 4. The polyoxymethyleneoxazolidines preferably contain a total of not more than six oxymethylene units (--CH 2 O--) in one or more ring substituents.
