Abstract
Cationic nitrogen-containing polymers are obtained by reacting a polyhydric polymer or a proteinaceous material with cyanamide or a salt thereof in an aqueous acid medium containing sufficient acid to provide at least one equivalent of acid for each equivalent of cyanamide and including, when a cyanamide salt is used, sufficient acid to neutralize the salt and an amount of water sufficient to swell the polymer or protein but not exceeding the amount required to dissolve it. The protein may be corn, wheat or soya flour or gluten or casein from milk or cheese. The polyhydric polymer can be polyvinyl alcohol or a cellulose or another polysaccharide, corn starch being exemplified. The weight ratio of polymer to cyanamide may be 0.5-10:1. The acid may be added in the form of an acid salt of cyanamide and sufficient to give a pH less than 1. In some examples glacial acetic acid is added as diluent.ALSO:Cationic nitrogen-containing polymers are obtained by reacting lignin with cyanamide or a salt thereof in an aqueous acid medium containing sufficient acid to provide at least one equivalent of acid for each equivalent of cyanamide and including, when a cyanamide salt is used, sufficient acid to neutralize the salt and an amount of water sufficient to swell the lignin but not exceeding the amount required to dissolve it.
