In the present investigation a novel interpenetrating polymer
network of Gum tragacanth, poly(acrylic acid) and poly(acrylam-
ide) has been synthesized using lipase as an initiator and
glutaraldehyde as a crosslinker. The present IPN was synthesized
using enzyme as an initiator rather using chemical initiator. The
E-mail biodegradability of the candidate polymer has been studied
through soil burial and composting method. The candidate
polymer has been evaluated as a device for controlled release of
urea and enhancement of moisture content of soils.
