    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 the (meth)acrylic ester of a saturated alcohol (G) and the urethane-containing alcohol (A) are passed continuously through at least one fixed bed reactor filled with an immobilized enzyme (E) as a catalyst.
