    摘要: A process for preparing urethane-containing (meth)acrylic esters (U) by reacting a urethane-containing alcohol (A) with a (meth)acrylic ester of a saturated alcohol (G) in the presence of at least one polymerization inhibitor (P) with an enzyme (E) as a catalyst in a reactor, wherein a) the saturated alcohol released and any entraining agent used form an azeotrope with the excess corresponding (meth)acrylic ester (G), the azeotrope is removed by distillation under reduced pressure and b) at least a substream from the bottom of the reactor is circulated via the top of the distillation column.
