Abstract

Processes for enzymatic synthesis comprising: (a) providing an aliphatic poly(oxyalkylene)amine; and (b) reacting the aliphatic poly(oxyalkylene)amine with a reactant selected from the group consisting of acrylic acid compounds and alkyl esters thereof, in the presence of a hydrolase in bulk or in a liquid reaction medium comprising an organic solvent to for a poly(oxyalkylene)acrylamide.
