    摘要： High-solids binder combinations comprising polyisocyanates, special lactone-based polyols and polyacrylate-polyols, a process for preparing such binders, and their use for producing coatings.The lactone-based polyols include ε-caprolactone-based polyols having an average hydroxy functionality ≧2 and a number-average molecular weight of from 119 to 2000 g/mol. The polyacrylate resins are prepared by copolymerizing optionally functional polybutadienes, aromatic monomers, hydroxyalkyl esters of acrylic or methacrylic acid having primary hydroxyl groups, aliphatic esters of acrylic or methacrylic acid and C1 to C8 monoalcohols, α,β-unsaturated C3–C7 monocarboxylic or dicarboxylic acids or of one or more monoesters of maleic acid or fumaric acid and C1 to C14 monoalchols.

    摘要： A process for the production of aliphatic oligocarbonate diols is disclosed. The optionally catalyzed high yield process entails the multistage transesterification of aliphatic diols with dimethyl carbonate. In the process DMC-methanol mixtures that have been distilled off are recycled to the reaction solution with further conversion and depletion of the contained DMC in the same or in a following reaction batch.
