Abstract: A semi-continuous process for the preparation of polyurethane ionomer or polyurethane-urea ionomer aqueous dispersions which comprises:A. in a first reaction zone contacting (i) an excess of an aliphatic or cycloaliphatic diisocyanate, or mixture of an aliphatic or cycloaliphatic diisocyanate with an aromatic diisocyanate; (ii) an organic polyol, and (iii) a difunctional isocyanate-reactive component containing an ionic group or potential ionic group, under conditions such that an isocyanate terminated ionic prepolymer is formed; with the proviso that where an aromatic diisocyanate is used the equivalents of aromatic diisocyanate used are less that the equivalents of the organic polyol and difunctional isocyanate-reactive component;B. transferring the prepolymer to a second reaction zone;C. in the first reaction zone or the second reaction zone contacting the prepolymer with a neutralizing agent under conditions such that the ionic groups are neutralized;D.

Abstract: The invention relates to bulk polyurethane ionomers prepared by the reaction (A) an isocyanate terminated ionic prepolymer with (B) a hydrocarbon polyol chain extender, said prepolymer having been prepared from (i) an excess of diisocyanate, (ii) a mixture comprising a diol and an organic polyol having three or more reactive hydroxyl moieties each having a molecular weight of from about 250 to about 6,000 and (iii) a difunctional isocyanate-reactive component containing an ionic group or potential ionic group.

Abstract: Disclosed is dispersion of a polyurethane-urea polymer in a continuous phase. This dispersion contains about 0.1 to about 5 parts by weight of an ionizable, non-volatile salt per 100 parts by weight of polyurethane-urea polymer. Polyurethane-urea coatings made from this dispersion have excellent static dissipative properties.

Abstract: Disclosed are novel stable aqueous dispersions of ionic polyurethane-polyureas prepared from (A) aqueous dispersions of isocyanate terminated ionic prepolymers and (B) hydrocarbon polyamine extenders. The novelty resides in employing a mixture of a diol and triol in the prepolymer forming step. Also disclosed are the films and coated substrates obtained through the use of said dispersions as coatings.

Abstract: Novel compounds having the formula ##SPC1##Wherein R is an alkyl group of 1 to 5 carbons, X is Br or Cl and Y is Cl or is Br except when X is Cl, are prepared by the reaction of a hydrazine source material with a corresponding compound of the formula ##SPC2##The product compounds are fungicidal in their own right and are readily oxidized to highly active trihalo-4-alkylsulfonyl pyridine fungicides.

Abstract: The invention comprises a process for producing ring-perchlorinated aromatic carbocyclic and N-heterocyclic isocyanates by the vapor phase chlorination of the corresponding acetamido-substituted carbocycle or N-heterocycle. The resulting isocyanate may be further reacted with an active hydrogen-containing compound to form the corresponding carbamate, thiocarbamate, urea, or the like. The invention further comprises certain novel compounds made by such process, said compounds being useful as intermediates for plastic materials or as fine retardant additives in plastics.

Abstract: The invention is a genus of compounds of the formula ##SPC1##Wherein Y is H, M or RCO--; R is a primary or secondary C.sub.1 -C.sub.12 alkyl group, a C.sub.5 -C.sub.7 cycloalkyl group, phenyl or a C.sub.7 -C.sub.12 phenalkyl or alkylphenyl group and M is a metal or ammonium cation. The compounds have utility as intermediates and as herbicides.
