    摘要： An object of the invention is to provide a decomposing system for polyisocyanate residues that is capable of suppressing reaction of polyisocyanate residues with high temperature and high pressure water to allow smooth start-up of the operation, and a start-up method for the decomposing system for the polyisocyanate residues. The decomposing system is used for hydrolyzing the polyisocyanate residues to polyamine using high temperature and high pressure water, comprising a hydrolyzer, a water feed pipe connected to the hydrolyzer, a residual feed pipe connected to the water feed pipe, a solvent feed line for filling an organic solvent in a solvent filling portion of the residual feed pipe, and a solvent draining line. Upon start-up of the operation, the organic solvent is previously filled in the solvent filling portion via the solvent feed line and the solvent draining line, first, and then, the high temperature and high pressure water is fed from the water feed pipe to the hydrolyzer. Then, the organic solvent is fed from the residual feed pipe to the water feed pipe, first, and then, the polyisocyanate residues are fed thereto.

    摘要： A (meth)acrylate-grafted polyether polyol produced by reacting 40 to 95 parts by weight of a polyoxyalkylene polyol and 5 to 60 parts by weight of a vinyl monomer, both relative to 100 parts by weight of the sum total of the polyoxyalkylene polyol and the vinyl monomer, and 0.1 to 5 moles of an alkyl peroxide as a radical initiator per mole of the hydroxyl group in the polyoxyalkylene polyol, wherein the polyoxyalkylene polyol has a hydroxyl number of 25 mg KOH/g or less, and the vinyl monomer contains a (meth)acrylate and/or a hydroxyl-containing (meth)acrylate in an amount of 50% by weight or higher. The (meth)acrylate-grafted polyether polyol is excellent in colorless-transparency, compatibility, mechanical strength, weather resistance, and blending resistance, and therefore is useful as a raw material for a polyurethane resin cured article.

    摘要： An apparatus for continuously producing polyisocyanate is provided for quickly contacting polyamine and carbonyl chloride in order to suppress an undesirable reaction between polyamine and polyisocyanate so that a by-product can be reduced and the yield of polyisocyanate can be improved. In a circulatory line 7, a material-mixing portion 8, a high-shear pump 3, a reactor 4, a liquid-feeding pump 5 and a cooler 6 are interposed in series along the direction of the flow of a reaction solution, thereby forming a closed line. In this apparatus 1, after polyamine and carbonyl chloride are supplied in the material-mixing portion 8, the reaction solution is sheared by the high-shear pump 3 in a state where the contact of the polyamine with the reaction solution is minimized. Thus, the formation of a urea compound as a by-product can be suppressed and the yield of polyisocyanate can be improved.
