Abstract: A water-dispersible hot melt adhesive comprises 75-95 parts of a graft copolymer of about 40-80% vinyl monomer and about 20-60% by weight of water-soluble polyalkylene oxide polymer, and 5-25 parts by weight tackifying resin. The water-soluble polyalkylene oxide polymer has a molecular weight of about 3000 to 20,000 and a polymerized ethylene oxide content of at least 50% by weight. The vinyl monomer is preferably a vinyl acetate or low molecular weight alkyl-substituted acrylate. The adhesive is preferably 7585% copolymer and 15-25% by weight tackifying resin.

Abstract: A process for preparing cationic thermosetting resins by reacting a polyalkylene polyamine with a dicarboxylic acid reagent and optionally with a lactone, an alkyl ester of acrylic or methacrylic acid, or a lactam, to prepare a polyamidepolyamine intermediate and thereafter reacting the intermediate with epichlorohydrin; said reactions being conducted under controlled concentration ranges, reaction time and temperatures, and molecular weight values. Aqueous solutions of the resulting resins display excellent stability at high total solids contents and are useful in a number of applications such, for example, as wet strength and pigment retention additives in the paper making process.
