Abstract: 1442569 Aqueous polyurethane emulsions HODOGAYA CHEMICAL CO Ltd 24 Oct 1974 46112/74 Heading C3R An aq. polyurethane emulsion is made by dispersing in an aq. alkaline solution a carboxylmodified isocyanate prepolymer (P), having a COOH and #2 NCO groups, made by (1) reacting a polyol with a dicarboxylic acid anhydride to form a semi-ester (E), and (2) reacting (E) with a polyisocyanate (I). Reaction (1) may be performed at 60-130‹ C., there being no reaction between OH groups and COOH groups liberated by alcoholysis of the anhydride. Reaction (2) may be performed at 70-100‹ C. NCO/OH mole ratio may be #2À0, and in (P), COOH content may be 0À1-3À0%. (P) may either be preformed or be formed in situ by dispersing (E) and (I), consecutively or as a mixture, in the alkaline solution. The alkali may be inorganic or organic. Polyisocyanate (I) may be monomeric, or may be a prepolymer formed from a polyol and a monomeric polyisocyanate. In the examples, acid anhydrides are maleic, glutaric, succinic, or phthalic; polyols are polypropylenepolyether triol or glycol, polyethylene polyether triol, glycerol, castor oil, or trimethylolpropane; monomeric polyisocyanates are TDI, HMDI, or PPI. Mixtures of 2 semi-esters or of 2 polyisocyanates may be employed. The alkali may be NaOH or NH 4 OH. Use.-Paints or coatings for cloth, paper, leather, wood, or metal; impregnants, binders, adhesives, tackifiers.

The polyoxymethylene resins are polymers and copolymers in which all of the recurring units have the formula <FORM:0993602/C3/1> where R1, R2 and R3 are selected from hydrogen, lower alkyl and halogen substituted lower alkyl radicals and where n is zero or an integer from 1 to 3 and where n is zero in 85% to 100% of the recurring units.  Suitable blowing agents are water, ketones, alcohols such as ethanol, butan-2-ol, aldehydes such as acetaldehyde, esters such as ethyl acetate, halogenated hydrocarbons such as dichlorodifluoromethane, dichloromethane, chloroform, ethyl chloride, fluorotrichloro methane, 1: 1: 1-trichloroethane, 1: 1: 2 - trifluoroperchloroethane, nitriles such as acetonitrile, gases such as carbon dioxide, nitrogen, ammonia, formaldehyde, aqueous solutions of formaldehyde, ammonia and methyl ethyl ketone.

[Also in Division G1] In apparatus for sealing off the ends of hollow bodies, e.g. hollow tubes during testing, and simultaneously clamping them, the pressure medium is applied to a sealing ring 7 which surrounds the tube and via a ring 8 and wedge elements 4a-4d to axially slidable clamping elements 3a-3d which are moved to the right as in Fig. 1, to grip the tube. Pivoted double levers 13 are provided on the housing such that one end engages the clamping elements 3a-3d and the other end is connected to a spring- loaded plunger, such that, on increase in pressure of the pressure medium, the lever 13 is caused to pivot by the moving clamping element, so as to stress the spring 9, and on decrease in pressure of the pressure medium, the tension of the spring causes the lever to return the elements to their initial positions. Similarly, the wedge elements 4a-4d move against the action of spring 10. The wedges and clamping elements have interengaging slots and projections to prevent the clamping elements falling inwards on withdrawal of the pipe. The pipe may be flushed with the pressure medium before the sealing head is applied.
