  • Patent number: 4435526
    Abstract: Novel polymers of excellent heat- and flame-resistance are obtained by reacting together an aqueous solution of an aminoplast precondensate such as a urea-formaldehyde syrup, an organic polyisocyanate comprising di(isocyanatophenyl)methane or a mixture of di(isocyanatophenyl)methane with poly(isocyanatophenyl)polymethylenes, and an isocyanate-reactive organic polyol in the presence of a tertiary amine as catalyst and a poly(haloalkyl)phosphate, especially tris-(2-chloroethyl)phosphate.Under normal circumstances, foamed materials are obtained, but non-foamed materials can be obtained by carrying out the reaction in the presence of a CO.sub.2 absorbent.
    Type: Grant

    Assignee: Abelard Management Services Limited
    Inventor: Alan M. Wooler
  • Patent number: 4249949
    Abstract: Self-setting compositions are formed by bringing into admixture an organic polyisocyanate, a non-ionic surface active agent devoid of isocyanate-reactive groups, an alkaline filler and water. Preferred alkaline fillers are portland cement, calcium oxide and hydrated lime. A plasticizer is preferably incorporated in the composition. Waste material, for example liquid or particulate radioactive wastes may be formed into a self-setting composition for consolidation and disposal. A particulate extender may be incorporated in the self-setting composition to give a product useful for example as a floor screed or cavity filler.

    Assignee: Imperial Chemical Industries Limited
    Inventors: Alan M. Wooler, Olle Bengtson
  • Patent number: 4234693
    Abstract: A process for the manufacture of polyurea foams which comprises reacting an organic polyisocyanate with at least a chemically equivalent amount of water in the presence of an imidazole compound.
    Type: Grant
    Filed: June 14, 1976
    Date of Patent: November 18, 1980

    Inventor: Alan M. Wooler
  • Patent number: 4110397
    Abstract: An improvement is provided in moulding processes for composite bodies or sheets, especially chipboard, made from mouldable compositions in which an isocyanate-based binding agent is used, the improvement being the provision of a metallic soap at the interface of the composition and mould surface to assist release.
