    摘要: The invention relates to acryloyl-containing polyesters having acid numbers AN of 1-50 mg of KOH/g of substance and having been polymerized from cocondensed units of(A) 1.0 mole of at least one dicarboxylic anhydride,(B) 0.02-0.08 mole of at least one saturated dihydric polyether alcohol having a molecular weight Mn of about 1,000 to 2,000,(C) 0.48-0.42 mole of at least one dihydric saturated alcohol,(D) 1.0 mole of at least one trihydric saturated oxyalkylated alcohol with a degree of oxyalkylation of 2-6, up to 50 mole-% of said oxalkylated alcohol may be replaced by a trihydric, saturated, non-oxalkylated alcohol, and(E) 1.0-2.0 moles of acrylic acid, to a process for their preparation, and to their use as radiation-curable binders in aqueous emulsion preferably for coating wood and woodlike materials, for which the presence of customary external surface-active agents and reactive radiation-curable diluents is not necessary.
