Abstract

Abstract Biocidal compositions useful in controlling the growth of bacteria and fungi in aqueous surface coatings are aqueous solutions that contain from 20 percent to 80 percent by weight of bicyclic polyoxymethyleneoxazolidines having the structural formula ##STR1## wherein each R represents hydrogen, alkyl of 1 to 6 carbon atoms, phenyl, halophenyl, or --(CH 2 O) m 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.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 89 words
A biocidal composition for use in inhibiting the growth of bacteria and fungi in aqueous surface-coating compositions that is an aqueous solution containing 20 percent to 80 percent by weight of a biocidal component that comprises a bicyclic polyoxymethyleneoxazolidine having the structural formula ##STR4## wherein each R represents hydrogen, alkyl of 1 to 6 carbon atoms, phenyl, halophenyl, or --(CH 2 O) m 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.
Claim 2
Dependent Claim 89 words
A biocidal composition for use in inhibiting the growth of bacteria and fungi in aqueous surface-coating compositions that is an aqueous solution containing 20 percent to 80 percent by weight of a biocidal component that comprises a bicyclic polyoxymethyleneoxazolidine having the structural formula ##STR4## wherein each R represents hydrogen, alkyl of 1 to 6 carbon atoms, phenyl, halophenyl, or --(CH 2 O) m 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.
Claim 3
Dependent Claim 19 words
A biocidal composition as defined in claim 1 that contains 40 percent to 60 percent of said biocidal component.
Claim 4
Dependent Claim 32 words
