Abstract: A process for the preparation of curable etherified aminoplast resins based on urea/aldehyde polycondensates, and the preparation of surface coating resins. Urea is first reacted with an alpha , alpha -dialkylaldehyde, as much as 50 mol % of which may be replaced by formaldehyde, in a molar ratio urea/aldehyde of about 1:2, at from 50 DEG to 120 DEG C., in the presence of an acid and in the presence or absence of an alcohol or of other organic solvents, and the 2-oxohexahydropyrimidine derivative obtained in this cyclocondensation is then condensed with formaldehyde in the presence of one or more alcohols and an acid. These aminoplast resins are useful as both acid-curable resins and as resins for baking finishes.

Abstract: A process for the continuous polymerisation of vinyl monomers with formation of vinyl polymers having a molecular weight of Mn = 1000 to 20,000, characterised in that the polymerisation is carried out in an annular gap reactor with a gap of from 0.5 to 10 mm in width, in that the annular gap is delimited on the inside by a rotor, and in that the polymerisation is carried out at a temperature of from 110 to 270 DEG C.

Abstract: Radiation-curable urethane acrylate compounds containing amine and urea groups and based on diisocyanates or polyisocyanates, hydroxyl compounds and amines, characterised by a content of secondary or tertiary amino groups which are bonded to isocyanate via hydroxyl groups and are obtainable by the addition reaction of primary or secondary amines with hydroxyacrylates.
