US Classification:

514 55, 435 681, 435 72, 435 74, 435101, 527200, 527206, 527303, 536 20, 536 551, 536 553, 536127

Abstract:

The present invention is directed to homogeneous phase enzyme-catalyzed processes for producing modified chitosan polymers or oligomers. An enzyme is reacted with a phenolic substrate in the presence of a chitosan polymer or oligomer to produce a modified chitosan polymer or oligomer. The invention also includes modified chitosan polymers or oligomers produced by the novel processes, in particular modified chitosan polymers or oligomers having useful functional properties, such as base solubility and/or high viscosity.
