Insoluble porous polymeric-phenolic complexes

Claim 2

Porous granules or beads comprising a complex compound of a phenolic material containing a phenolic hydroxyl group with a water insoluble but water swellable crosslinked polymer of an N-vinyl lactam or an N-actyl-N-vinyl amide.

Claim 3

The granules or beads of claim 1 wherein the phenolic material is selected from the group consisting of 8-hydroxyquinoline, n-heptyl-p-hydroxybenzoate, 4,6-dinitro-o-sec-butylphenol, trichlorophenol, 2,2'-thiobis(4,6-dichlorophenol), N-alkyl-N-vinyl hydroxy anisole, 2,6-di-tert-butyl-p-cresol, 4-n-hexylresorcinol, and phenol.

Claim 4

A process for preparing the grnaules or beads of claim 1 which comprises complexing reacting porous granules or beads comprising said water insoluble, but water swellable, crosslinked polymer of an N-vinyllactam or an N-alkyl-N-vinyl amide with a solution of said phenolic material for a time sufficient to produce said complex compound.

Claim 5

The product of claim 1 wherein the porous granules or beads comprises a complex compound of a soluble compound containing a phenolic material selected from the group consisting of phenol; resourcinol; hydroquinone; salicyclic acid; nonylphenol; cresol; 8-hydroxyquinoline; 8-hydroxyquinoline hydrochloride; 4-nitrophenol; phloroglucinol; dichlorphene; gallic acid; 1,5-dihydroxynaphthalene; pyrogallol; catechol; hexachlorophene; o-chlorophenol; 4-chlorocresol; 3-aminophenol butyl hydroxyanisole; 2-nitrophenol; n-heptyl-p-hydroxy benzoate; 2,6-di-tert-butyl-cresol; 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid; 2,4-dihydroxy benzophenone; 2-hydroxy-4-methoxy-benzophenone; 2,2'-dihydroxy-4,4'-dimethoxy-benzophenone; 2,2',4,4'-tetrahydroxy benzophenone; sodium 2,2'-dihydroxy-4,4'-dimethoxy-5-sulfo-benzophenone; and a water insoluble, but water swellable, [0.1 to 20% by weight] cross-linked polymer of an N-vinyl lactam monomer selected from those haing the formula ##EQU3## wherein R 1 and R 2 are selected from the group consisting of hydrogen, alkyl, and aryl; Y is selected from the group consisting of --O--, --S--, --SO 2 --, ##EQU4## and n and n 1 are integers from 0 to 5 provided that only one of n and n 1 may be zero, or a 0.1 to 20% by weight cross-linked polymer of a n-alkyl-N-vinyl-amide monomer selected from those having the formula: ##EQU5## wherein R 3 and R 4 are independently a hydrocarbon radical of 1 to 4 carbon atoms; said polymers being cross-linked with between about 0.1 to about 20% by weight cross-linking agent.
