Coumarins are well known for their antioxidant and anti-edema activities. Their antioxidant property gets enhanced with a methyl group at the C-4 position of the pyran ring. To increase the antioxidant potential and their hydrophilicity, a lipase (Novozyme 435) catalyzed copolymerization of 4-methylcoumarin diesters and polyethylene glycols (PEGs) has been carried out to give novel copolymers.
