摘要:
The present invention relates to a process for preparing highly functional hyperbranched polyesters which comprises reacting a reaction solution comprising solvent and (a) one or more dicarboxylic acids or one or more derivatives thereof with one or more at least trifunctional alcohols (b) or one or more tricarboxylic acids or higher polycarboxylic acids or one or more derivatives thereof with one or more diols (c) or one or more tricarboxylic acids or higher polycarboxylic acids or one or more derivatives thereof with one or more at least trifunctional alcohols (d) or one or more di- or polyhydroxycarboxylic acids (e) or one or more hydroxydi- or hydroxypolycarboxylic acids or mixtures of at least two of the above reaction solutions in the presence of an enzyme at temperatures above 60° C. and pressures above 500 mbar
摘要:
The invention relates to a method for the treatment of surfaces of wood or woodbase materials with surface treatment compositions, and the timbers or woodbase materials thus treated by impregnating with a curable aqueous composition of α) low molecular weight compounds V which have at least two N-bonded groups and/or β) precondensates of the compound V and/or γ) reaction products or mixtures of the compound V with at least one alcohol which is C1-C6-alkanols, C2-C6-polyols or oligoalkylene glycols; treating that impregnated material at elevated temperature and) treating at least one surface of the wood or woodbase material to be treated with a surface treatment composition.
