Polyvinylamide polymers containing polymerizable functionalities
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. where x+y+z+a=100.
