    摘要： This invention relates to polyurethane(urea) encapsulated fertilizer particles which exhibit slow-release properties and to a process for their production. In one embodiment, the process comprises a) applying a polyisocyanate component to fertilizer particles to form isocyanate coated fertilizer particles, b) mixing an inert inorganic filler with said isocyanate coated fertilizer, c) adding an isocyanate-reactive component to the mixture of step b) and d) allowing the reactive components to react to form filler containing polyurethane(urea) encapsulated fertilizer particles containing from about 1 to about 15 percent by weight of filled polyurethane(urea), said percent by weight based on the total weight of the encapsulated fertilizer, with the proviso that the weight ratio of polyurethane(urea) to filler is from about 80:20 to about 30:70.

    摘要： A polyurethane-forming reaction mixture characterized by its ability to be adjusted with respect to its viscosity in response to changing temperature and humidity conditions is achieved with a mixture that includes a liquid polyisocyanate having an isocyanate group content of at least 10% by weight, an isocyanate-reactive component which includes at least one high molecular weight polyol, a urethane catalyst and from 0.2 to 5 parts by weight per 100 parts by weight of isocyanate reactive component of a viscosity adjusting component. The viscosity adjusting component is preferably a diamine, a polyamine and/or an amine-terminated polyol. This reaction mixture is particularly useful for producing polyurethane geotextile composite materials useful as liners for ditches and canals.

    摘要： This invention relates to a process for the production of an optically clear, light-stable polyurethane-urea elastomer having an onset softening point of at least 130° C., processed at ambient temperature and casted in a mold at an isocyanate index of 95 to 120. This process comprises reacting: A) a liquid polyisocyanate or polyisocyanate prepolymer having an NCO group content of about 5 to about 50%, an average functionality of 2 to 3, a viscosity of less than 5,000 mPa.s at 25° C.; and B) an isocyanate-reactive component; in the presence of C) at least one organometallic catalyst. The present invention also relates to the optically clear, light-stable polyurethane-urea elastomers produced by this process.
