Abstract
Cyclic amine monomers and polymers and N-halamine biocidal polymer compounds are provided. Representative monomers have the structure: ##STR1## wherein R.sup.1 is selected from the group consisting of hydrogen and from C.sub.1 to C.sub.4 alkyl; R.sup.10 is a bond or parasubstituted phenyl; and R.sup.11 is cyclic amine unit of a 5- to 6-membered heterocyclic ring selected from the group consisting of: (a) 1,3,5-triazine-2,4-dione; (b) 3,4,5,6-tetrahydro(1H)pyrimidin-2-one; and (c) 2-oxazolidinone; R.sup.10 is attached to a linkage carbon of R.sup.11, wherein said linkage carbon of R.sup.11 is a carbon located on the ring of R.sup.11 and is substituted with a substituent selected from the group consisting of C.sub.1 -C.sub.4 alkyl, benzyl, and alkyl-substituted benzyl; from 0 to 2 non-linkage carbon members are a carbonyl group; and from 0 to 1 non-linkage carbon member is substituted with a moiety selected from the group consisting of C.sub.1 -C.sub.4 alkyl, phenyl, alkyl-substituted phenyl, benzyl, alkyl-substituted benzyl, pentamethylene in spirosubstituted form and tetramethylene in spirosubstituted form. The cyclic amine monomers and polymers can be utilized to form the biocidal…
