摘要： Open-cell structures are filled with polyimide foam formed in place by the use of a foam precursor in powdered form comprised of a combination of (a) the reaction product of an excess of organic polyisocyanate and a member selected from the group consisting of furfuryl alcohol and condensation products thereof, and (b) an organic polycarboxylic compound containing two carboxylic anhydride groups. The precursor is prepared by combining the species under conditions which favor the reaction of the furfuryl alcohol with the polyisocyanate, but not the polyimide-forming reaction. The polyimide-forming reaction itself is then performed by adding preselected amounts of the powdered precursor, depending on the desired ultimate density of the foam, to each cell of the open-cell structure, then heating to initiate the polyimide reaction, and permitting the carbon dioxide generated by the reaction to escape while confining the resulting foam to the cells.

摘要： A novel composition of matter is provided, which comprises certain polydiene-functionalized polyisocyanate oligomer and certain polydieneophile-functionalized epoxy-amine adduct, which polyisocyanate oligomer and epoxy-amine adduct are reactive at elevated cure temperature. The polydieneophile-functionalized epoxy-amine adduct comprises the reaction product of certain polyhydroxy functional epoxy-amine reactant with dieneophile functional mono-isocyanate reactant. The polydiene-functionalized polyisocyanate oligomer comprises the reaction product of polyisocyanate reactant, preferably a triisocyanate, with approximately equal molar equivalent amount of monohydroxy diene reactant or monoamino diene reactant or like isocyanate-reactive diene reactant. The crosslinkable composition of matter is useful in coating and other applications, especially cathodic electrocoating applications.

摘要： The invention relates to a process for the preparation of aqueous dispersions to be further processed to electrocoating paints with baking temperatures below 160.degree. C. and baking times.ltoreq.30 minutes, which dispersions contain modified epoxide-amine adducts as binders and polyisocyanates blocked by hydroxyl groups as cross-linking agents.In this process polyepoxides and compounds containing one or more, preferably 2, hydroxyl groups per molecule are reacted at elevated temperatures in the presence of catalysts to furnish epoxide-containing intermediates.A solvent or a mixture of solvents is then added with external cooling ahd the solution is boiled under reflux, if necessary in vacuo, until the temperature of the solution drops to 95.degree. C. to 20.degree. C.Amines are then added onto the epoxide groups which are still present in a free state in the epoxy resin and a dispersion is prepared by adding a water/acid mixture after adding the crosslinking agent or the dispersion is first prepared and the crosslinking agent is added subsequently.
