Abstract: A cleaning tablet comprising a hydrogen-bonded complex of poly(N-vinyl pyrrolidone) containing, by weight, about 15-20 wt. % H2O2, and ingredients capable of producing an effervescent effect in aqueous solution by release of carbon dioxide therefrom which comprises an alkali carbonate and/or bicarbonate base and an organic acid.

Abstract: The present invention relates to a polymerizable polymer formed from an N-vinyl amide monomer and containing a polymerizable functionality. In one approach, a dual functional monomer may be employed. In the case where the dual functional monomer incorporates glycidyl methacrylate, a third polymerizable monomer is also included. In a second approach, a monomer with polymerizable functionality can be grafted onto a pre-existing, suitable N-vinyl amide co-polymeric material, yielding a co-polymer comprising a polymerizable functionality.
