    摘要: Polyamines having primary amino groups, preferably aromatic amino groups, are prepared in a one-stage process by hydrolyzing compounds containing terminal isocyanate groups. The polyamines produced are useful for preparing polyurethane ureas, which can be used in turn for producing coatings or porous (foams) or non-porous moldings.

    摘要: Dispersions of hybrid polyurethane particles are made using miniemulsion techniques. An isocyanate-terminated prepolymer and a monomer are mixed and dispersed in an aqueous phase to form a dispersion of droplets. All droplets are polymerized and chain-extended in one step to form hybrid particles containing a polyurethane and a polymer of the monomer. This process provides a simple method of making hybrid particles, in which particle size and the number of particles is controlled in the mixing step. The hybrid particles often have a core-shell morphology, with the polyurethane being concentrated in the shell and the polymer being concentrated in the center of the particle.

    摘要: A lignocellulosic composite article includes a plurality of lignocellulosic pieces and an adhesive system disposed on the plurality of lignocellulosic pieces for bonding the plurality of lignocellulosic pieces. The adhesive system includes a binder component and a compatibilizer component. An example of a suitable binder component is an isocyanate component, e.g. a diphenylmethane diisocyanate (MDI), a polymeric diphenylmethane diisocyanate (pMDI), and combinations thereof. The compatibilizer component includes a trialkyl phosphate. The compatibilizer component is utilized in an amount of at least about 0.5 parts by weight based on 100 parts by weight of the binder component. The compatibilizer component is useful for reducing the amount of press time required during manufacture of the composite article. The adhesive system can include additional components, such as an isocyanate-reactive component. The composite article may be various lignocellulosic composites, such as oriented strand board (OSB), particleboard (PB), fiberboard (e.g. medium density fiberboard; MDF), etc.
