Abstract
Poly(beta-malic acid) was prepared by lipase-catalyzed ring-opening po lymerization of benzyl beta-malolactonate with subsequent debenzylatio n. Benzyl beta-malolactonate was readily polymerized by porcine pancre atic lipase or Novozyme 435 lipase at 60 degrees C to yield poly(benzy l beta-malate) having a molecular weight of greater than 7000.
