    • Novel starch-based glue paste compositions are disclosed composed of (i) a carrier paste containing 5 to 16 wt % of a starch selected from the group consisting of corn starch, wheat starch, rye starch, oat starch, barley starch, potato starch, tapioca starch and pea starch, each being native starch or chemically modified starch, or any mixture thereof and (ii) a main paste with a total starch content of 25 to 50 wt % composed of a mixture of 10 to 30 wt % native rice starch or an acetylated version thereof having an amylose content of 12 to 20 wt %, 1 wt % other compounds and a complementary amylopectin content of 87 to 79 wt %, and 90 to 70 wt % of a starch or mixture of starches selected from the above defined group. Processes for the manufacture of the novel glue paste compositions based on the Stein-Hall method are disclosed, as well as a premix of starches for said manufacture. The glue paste compositions present excellent film forming and glueing properties and are particularly suitable for the manufacture of laminated corrugated board.

    • An amylose aqueous dispersion of pH at least 9.5 contains (a) paraformaldehyde or an operable equivalent consisting of glyoxal, an aqueous solution of formaldehyde or methanolstabilized formaldehyde, or a non-polymerized urea-formaldehyde concentrate, and (b) urea or an operable equivalent consisting of succinamide, adipamide, or a basic nitrogen-containing compound which forms an N-methylol derivative with formaldehyde. The amylose may be pure amylose separated from a starch or may be a high-amylose starch containing at least 55% of amylose. Addition of the ureaparaformaldehyde system to the amylose dispersion stabilizes it against precipitation, and allows it to be used in adhesive formulations. The dispersion may also contain, as partial replacements of the urea, paraformaldehyde or operable equivalents, glyoxal, acetaldehyde, furfural, benzaldehyde, thiourea, a cyclic urea compound, a trimethylol alkyl or aryl compound, dicyandiamide, melamine, hydrazine hydrate, morpholine, ethylene glycol, a watersoluble alcohol, a ketone or a primary or secondary amine. The proportions of paraformaldehyde and urea (or operable equivalents) may be as much as 200 parts per 100 parts of amylose. Stabilizing salts may be added e.g. ammonium salts or chlorides, nitrates and acetates of alkali or alkaline earth metals. The alkaline pH of the dispersion may be maintained by addition of e.g. sodium and potassium hydroxides, or sodium carbonate silicate or phosphate. Formulation of an adhesive composition may be completed by adding to the stabilized amylose dispersion a filler e.g. clay, resins, and raw starch. In an example, a slurry of amylose, water and paraformaldehyde is heated to 330 DEG F. under pressure, cooled to 160 DEG F., and mixed at 160 DEG F. with urea and an alkali.
