    摘要: A process for preparing radiation-curable, urethane-functional prepolymers by reacting an isocyanate-functional component A with an OH-containing component B, wherein either component A embraces two different isocyanate compounds A1 or one isocyanate compound A1 and at least one isocyanate compound A2 or component B embraces at least two different compounds B1. Also, the prepolymers obtainable by the process and the radiation-curable formulations comprising them. Furthermore, the use of the radiation-curable formulations for coating substrates, a method of coating substrates, and the coated substrates themselves.

    摘要: Compounds having alcoholic hydroxyl groups are esterified with acrylic or methacrylic acid in the presence of copper(II) salts or mixtures thereof as polymerization inhibitors and in the presence of a hydrocarbon as a water-entraining agent with removal of the water of reaction at from 90 to 150° C. After the esterification, the copper salt is precipitated as copper sulfide and is separated off from the ester. The light-color (meth)acrylates resulting in the high yields are particularly suitable for coatings containing colored pigment on substrates such as wood, paper, mineral building materials, plastics or metal.
