Abstract

1,232,918. Paper. MITSUI TOATSU CHEMICALS, Inc. 12 Nov., 1969, No. 55467/69. Heading D2B. [Also in Division C3] Paper may be strengthened with a thermosetting polyurea polyamide.cocondensed resin prepared by deammoniating urea with a polyalkylene polyamine to form a product in which an amino group of the polyalkylene polyamine is terminal, reacting this product with an aliphatic dibasic acid to form a polyurea polyamide cocondensate and reacting the cocondensate with epichlorohydrin .to form the resin (see Division C3). In Examples a wood pulp is dispersed in water and to the dispersion a.polyurea polyamide cocondensed resin solution is added. Following addition of more water and of sodium carbonate the dispersion is made into paper on a conventional sheeting machine.
