Process for Preparing Epoxy Resin. This process combines epichlorohydrin, 2,2-bis(p-hydroxyphenyl)propane, and a solvent in the presence of alkali. A small initial amount of alkali is used while the mixture is held at 45°C to 70°C until it forms a homogeneous mass. Additional alkali is then added, and polycondensation proceeds under stirring at 70°C to 90°C to produce the epoxy resin.

Method for Preparing Biuret-Structure Polyisocyanates. This method reacts 1,6-hexamethylenediisocyanate with water vapor introduced into the reaction zone in a mixture with air or an inert gas. The reaction takes place at 150°C to 170°C, with the vapor mixture maintained at specified moisture and temperature conditions. The described process produces polyisocyanates with a molecular mass of about 800 and an isocyanate-group content of up to 23.59%, without forming polyurea. The patent description characterizes the method as single-stage, suitable for continuous operation, and technologically simple.
