Abstract
Disclosed are novel aminopolyamide-acrylamide-glyoxal resins useful as a sizing agent for paper having low water absorption, a desirable property for sized paper. The products are water dispersible and/or soluble and also find utility in printing inks, textile treatment and cosmetic or beauty aid compositions. The aminopolyamide is the condensation product of a polymeric fat acid and polyalkylene polyamine.
Claims8
An aminopolyamide-acrylamide-glyoxal resin prepared by reacting
- a. a polymeric fat acid aminopolyamide having an amide number of about 150 to 600
- b. an amount of an unsaturated amide sufficient to react with substantially all the amine groups in the aminopolyamide, said unsaturated amide having the formula ##STR3## where R'is hydrogen or an alkyl group containing up to 6 carbon atoms and c. reacting the resulting aminopolyamideunsaturated amide adduct with about 0.3 to 1.5 moles of glyoxal per amide group present in said adduct.
A process of preparing an aminopolyamide-acrylamide-polyaldehyde resin which comprises the steps of reacting
- a. a polymeric fat acid aminopolyamide having an amine number of about 150 to 600
- b. an amount of an unsaturated amide sufficient to react with substantially all the amine groups in the aminopolyamide, said unsaturated amide having the formula ##STR4## where R' is hydrogen or an alkyl group containing up to 6 carbon atoms and c. reacting the resulting aminopolyamideunsaturated amide adduct with about 0.3 to 1.5 moles of glyoxal per amide group present in said adduct.
