  • Patent number: 5003104
    Abstract: This invention involves a process for the carbonylation of a carbonylatable reactant, e.g., an alkyl ester, a dialkyl ether or mixtures thereof by reacting the same with carbon monoxide. The process comprises effecting the carbonylation in the presence of a solution of a catalyst system containing a rhodium compound, an iodide and a lithium component at a temperature of from 50.degree. C. to 400.degree. C. at a carbon monoxide partial pressure of 1 psig to 15,000 psig. Hydrogen may also be present. The invention also concerns a carbonylation catalyst system effective for the addition of carbon monoxide to a carbonylatable reactant which comprises a solution containing as essential components a rhodium containing active component, an iodide and a lithium component.

  • Patent number: 4125524
    Abstract: The present invention provides a process for the production of a polyester having an acid number which is not greater than 65 which comprises reacting an acid anhydride with a monoterminal epoxide in such a way that a self-sustaining reaction is initiated within 200 seconds of the reactants being mixed together and said reaction results in the attainment of a maximum temperature in excess of 200.degree. C within 200 seconds of initiation.

  • Patent number: 4125488
    Abstract: The invention provides a process for the production of a foamed polyester which comprises initiating a reaction between a poly-terminal epoxide, a mono-terminal epoxide and a cyclic diacid anhydride in the presence of a catalytically effective quaternary salt and a blowing agent, heating to a point at which the reaction becomes a self-sustaining exothermic reaction and controlling the reaction such that the temperature of the mixture is not reduced until after the exothermic reaction has begun to subside.

  • Patent number: 4086195
    Abstract: Bitumen filled polyester foams are provided through a process which comprises forming a solution of a bitumen having a softening point of at least about 80.degree. C. and a cyclic diacid anhydride at a temperature above the softening point of a bitumen, the bitumen solution is then mixed with a monoterminal epoxide and a polyterminal epoxide in the presence of a blowing agent resulting in the initiation of an exothermic reaction. The process for producing bitumen filled polyester foams through the in situ polymerization of polyesters in a solution of bitumen and the foams produced by the process constitute the invention.
