  • Patent number: 4870127
    Abstract: Novel acid-functional poly(alkylene carbonate) polyahls and their salts having surfactant activities are disclosed. These polyahls have, on the average, at least about 0.05 and up to about and including one hydrophilic terminus per molecule and can be produced by the reaction of a random non-ionic poly(alkylene carbonate) polyahl obtained by reacting a monofunctional alcohol, mercaptan, carboxylic acid, primary or secondary amine, alkyl substituted phenol or alkoxylates thereof with an alkylene carbonate and/or an alkylene oxide and/or carbon dioxide and/or a poly(alkylene carbonate) polyahl, and admixing a compound capable of adding an acidic end group thereto. Novel anionic poly(alkylene carbonate) polyahls are also disclosed. Surfactant compositions comprising the acid-functional polyahls of the invention and other non-ionic surfactants are also disclosed. Moreover, surfactant compositions comprising the novel acid-functional polyahls and other anionic surfactants are also disclosed.

  • Patent number: 4861909
    Abstract: Isocyanate-modified poly(alkylene carbonate) polyahls comprising the residue of at least one polyahl, at least one isocyanate modifier, poly(alkyleneoxy) units, poly(alkylene carbonate) units, and a plurality of active hydrogen end groups are disclosed. Also disclosed are isocyanate-functional prepolymer compositions of these isocyanate-modifed poly(alkylene carbonate) polyahls, which contain the residue of at least one isocyanate-modified poly(alkylene carbonate) polyahl of this invention and excess organic polyisocyanate units. Urethane/urea polymers formed by the reactions of the isocyanate-functional prepolymers with polyahls are also disclosed. Also disclosed are urethane/urea polymers comprising the residue of at least one isocyanate-modified poly(alkylene carbonate) polyahl of this invention, the residue of a polyisocyanate and the residue of at least one other polyahl selected from the group consisting of polyamines and polyfunctional hydroxyl compounds.
