3-Hydroxy-2-methylene-3-(1-naphthyl)propionic acid, methyl ester and fluorescent water soluble polymers prepared therefrom.

Fluorescent monomer and polymer

Polyacrylamide is reacted with formaldehyde and bisulfite at a temperature of at least about 100.degree. C. and at an initial reaction mixture pH of less than about 12, preferably about 3 to about 8, to produce sulfomethylpolyacrylamide.

Process for producing sulfomethylamide polymers

Sulfomethylamide-containing polymers

The methyl chloride or dimethyl sulfate quaternary ammonium salt of 1-methacryloyl-4-methyl piperazine.

Water-soluble cationic quaternary ammonium monomers

A high temperature, pressurized process is described to synthesize phosphonated acrylamide polymers represented by the structure: ##STR1## wherein X is from the group H, OR, Cl, Br, I, --COOM, --SO.sub.3 M, ##STR2## and mixtures thereof.

Phosphonic acid-containing polymer

Novel water-soluble polymers and copolymers are synthesized by the free radical polymerization of vinyl addition monomers described generally by the formula: ##STR1## wherein: M is hydrogen, lithium, sodium, potassium, ammonium, magnesium, or calcium;

Water-soluble sulfonated polymers

Novel water-soluble vinyl addition monomers are described generally by the formula: ##STR1## wherein: M is hydrogen, lithium, sodium, potassium, magnesium, or calcium;

New water-soluble sulfonated monomers

This invention concerns a new class of compositions for the sizing of paper and the method of treating paper using such compositions. Such new compositions comprise the reaction products of glyoxal and a hydrophobe which contains at least one hydroxyl group. Such compositions can be used either for internal or surface sizing.
