    摘要： A process for the production of compounds which crosslink under the effect of high-energy radiation containing isocyanurate groups, olefinic double bonds, and, optionally, blocked or free isocyanate groups by reacting(i) isocyanurate-group-containing polyisocyanates which are based on aliphatic and/or cycloaliphatic diisocyanates with(ii) compounds containing at least one isocyanate-reactive group and at least one olefinic double bond, such as hydroxyl-containing esters of acrylic acid and methacrylic acid with at least dihydric aliphatic alcohols having a molecular weight of from 62 to about 300,to form urethanes, the quantitative ratios between the reactants being selected so that for every free isocyanate group in component (i), the reaction mixture contains from about 0.9 to 1.5 hydroxyl groups of component (ii).The present invention also relates to the compounds prepared by this process and to the use of these compounds as the binder or a binder component in coating compositions crosslinkable by high-energy radiation.

    摘要： A process for the production of a crosslinkable low-molecular weight acrylic resin containing hydroxyl-groups and having a low-molecular consistency factor by the radical bulk copolymerization of(A) 0 to 30 parts by weight of a hydroxyalkyl ester of acrylic acid or methacrylic acid or mixtures thereof;(B) 0 to 60 parts by wt. of styrene or a substituted styrene or methyl methacrylate or mixtures thereof;(C) 10 to 90 parts by weight of an acrylic acid ester or of a methacrylic acid ester with 2 to 12 carbon atoms in the alcohol radical or mixtures thereof;(D) 0 to 30 parts by weight of an .alpha.,.beta.-monoolefinically saturated mono- or di-carboxylic acid with 3 to 5 carbon atoms or of a maleic acid semiester or mixtures thereof or reaction products thereof with a monoglycidyl compound, in the presence of 10 to 70 parts by weight of a monoallyl ether of an at least trihydric alcohol,The sum of the parts by weight of all the monomers A - E amounting to 100,Wherein the indicated quantity of monomer E is initially introduced and, at temperatures above 100.degree. C, monomers A to D together with 0.5 to 6% by weight, based on A to D, of an initiator with a half-life period at 100 to 160.degree. C of 0.01 to 100 minutes, are introduced over a period of 1 to 6 hours and polymerized, at least 98% by weight of the monomers A to D and from 36 to 95% by weight of monomer E being converted. Acrylate resins of this type are eminently suitable for the production of readily processible binder mixtures which although low in viscosity, have a very high solids content.

    摘要： The present invention is concerned with a process for producing biuret polyisocyanates and the polyisocyanates so produced. These isocyanates are produced by the reaction of at least about a four fold molar excess of a diisocyanate having aliphatically bound isocyanate groups with amino alcohols having a particular structure at a temperature between about 90 and 200.degree. C. The amino alcohols contain at least three carbon atoms, have their hydroxyl and amino groups separated by at least two carbon atoms, and may contain urea, urethane, ether or amino bonds. The present invention is also concerned with a process for producing two component and one component moisture curing lacquers using the biuret polyisocyanates of the present invention and the lacquers so produced.
