DEFINITION

Classification: 524/812

N-containing monomer other than unsubstituted ammonium as sole nitrogen, acrylamide, methylol acrylamide, acrylonitrile and the corresponding methacryl compounds or mixtures thereof:

(under subclass 804) Subject matter wherein there is at least one nitrogen containing monomer which is other than acrylamide, methylol acrylamide, acrylonitrile, methacrylamide, methylol methacrylamide, methacrylonitrile, monomer having NH4 as the sole nitrogen, or mixtures of any of these.
