    摘要: The use of polyisocyanates as binders in the preparation of particle boards is subject to the drawback that the boards exhibit a tendency to adhere to the face of the platens used in their formation. This problem is minimized by utilizing, in association with the polyisocyanate to be used as binder, minor amounts of one or more phosphates or thiophosphates of the formula: ##STR1## where R=alkyl (C.sub.3 and higher), alkenyl (C.sub.3 and higher), aryl, alkyl-substituted aryl, ##STR2## (where R.sub.2 is alkyl, aryl, or alkyl-substituted aryl, A and B are H, methyl, chloromethyl, 2,2,2-trichloromethyl, m=1-25) and lower-alkyl substituted by from 1 to 2 acyloxy groups where acyl is the residue of an aliphatic carboxylic acid having at least 2 carbon atoms; R.sub.1 is Cl, Br, lower-alkoxy, lower-alkylmercapto, arylamino, mono(lower-alkyl)amino, di(lower-alkyl)amino, hydroxy(lower-alkylene)oxy, aryloxy, hydrocarbylureido, and an enol residue; X=O or S and n=1 or 2. The polyisocyanates and the phosphates or thiophosphates are applied to the particles separately, or after preblending one with the other. Whether the components are applied separately or in combination one with the other, they can each be applied either neat or in the form of an emulsion or emulsions.

    摘要: A novel process is disclosed for the preparation of cyclic ureas having the formula ##STR1## wherein A is a straight chain alkylene radical of 2 to 4 carbon atoms, inclusive, wherein said alkylene radical can be substituted by at least one member selected from the group consisting of halogen, lower alkyl, lower alkoxy, aryl, aryloxy, aralkyl, and cycloaklyl. An alkylene diamine having the formula NH.sub.2 ANH.sub.2, wherein A is defined as above, is reacted in a solvent with carbonyl sulfide to form the corresponding N-(.omega.-aminoalkyl)thiocarbamic acid (NH.sub.2 ANHCOSH) or zwitterion thereof. The thiocarbamic acid is then heated to form the cyclic urea.The cyclic ureas are useful as cross-linkers and extenders in polyurethane formulations, and those ureas having 4 carbons in the alkylene chain find particular utility in the production of bis cyclic ureas which serve as masked isocyanate compounds in one-component polyurethane elastomer formulations.

    摘要: 1,3-alkylene-diazetidinediones-2,4, wherein alkylene contains at least 8 carbon atoms, are described. These compounds, which can be regarded as intramolecular dimers of alkylene diisocyanates, give rise to the latter on heating. Accordingly, these compounds are useful in a variety of situations in which it is desirable to have a compound which is stable on storage in admixture with other compounds such as polyols, polyamines and the like (which latter would react with a compound containing free isocyanate groups) but which can, at any desired moment, be converted by heating to the free diisocyanate. The latter then reacts with the other component(s) of the mixture to form a polymer.The above compounds are derived by cyclization of the appropriate cyclic allophanoyl halide.

    摘要: Novel araliphatic diisocyanates having the formulaOCN(CH.sub.2).sub.3 OArX(CH.sub.2).sub.3 NCOare disclosed wherein X is oxygen or a single bond and Ar is an arylene radical. The araliphatic diisocyanates are prepared from well known and readily obtainable starting materials. When X represents a single bond, the starting material is a monohydric phenol wherein a C-alkylation reaction followed by an O-alkylation reaction with acrylonitrile provides an intermediate dipropionitrile which is converted to the diisocyanate via phosgenation of the corresponding diamine. When X represents oxygen, the starting material is a dihydric phenol wherein O-alkylation with acrylonitrile provides the dipropionitrile which in turn is converted to the diisocyanate via the phosgenation of the corresponding diamine. The diisocyanates find particular utility in the preparation of color and light stable polyurethane products.
