    Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing a (meth)acrylic ester by which a light color esterification product is obtained in high yield. SOLUTION: This method for producing a (meth)acrylic ester comprises esterifying acrylic acid and/or methacrylic acid with at least one compound having at least one alcoholic hydroxyl group while adding to the reaction system a hydrocarbon with a boiling point of 60-140 deg.C as a water azeotropic agent at 90-150 deg.C in the presence of an acidic esterification catalyst and a polymerization inhibitor, and after esterification, distilling the water azeotropic agent and excess (meth)acrylic acid off at 90-150 deg.C under a normal or reduced pressure, and if necessary, neutralizing the product obtained after distillation with at least one basic inorganic compound, wherein a copper (II) salt or a mixture composed of the copper (II) salt and a copper (I) salt to be deposited after esterification as a copper sulfide and separated is used as the polymerization inhibitor.

    Abstract: PROBLEM TO BE SOLVED: To obtain a hardenable polyurethane polymer capable of providing an unhardened and dried coating film hardenable by radiation and having a good pendulum hardness, a high hardness and scratch resistance, and further capable of providing a hardened film having a high hardness and good flexibility by including a specific hydroxy-containing prepolymer in a specified proportion in a copolymerized state. SOLUTION: This hardenable polyurethane polymer comprises (A) 40-80 wt.% one or more kinds of OH group-containing prepolymers having one or more radically or photochemically polymerizable α,β-ethylenically unsaturated double bonds (based on the whole weight), (B) 0.1-20 wt.% one or more kinds of compounds having one or more isocyanate-reactive OH groups and/or primary or secondary amino groups, and further one or more polar functional groups, (C) 0.1-10 wt.% compound selected from a diamine, a polyamine and a mixture thereof, and (D) 10-50 wt.% one or more kinds of polyisocyanates in a copolymerized state. The OH value of the components A to C is 121-300 mg- KOH/g.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for separating an organic phase and an aqueous phase produced by an esterification. SOLUTION: At least one organic polymeric, anionic and water-soluble flocculant is used in a method for the phase separation of an organic-aqueous system containing unreacted residues of a carboxylic acid anhydride, a carboxylic acid or an alcohol used for producing an acrylate, a diacrylate, a (poly)ester acrylate or a (poly)ether acrylate and an acrylate which are substantially monomers. The flocculant is selected from a functional high-molecular weight polymer containing a carboxylic acid, a sulfonic acid, a phosphoric acid and/or a phosphonic acid functional groups and an anionic-modified polyacrylamide is preferred. The anionic flocculant has 4-22 Mda molecular weight.
