In the last few years new copolymeric supports for the immobilization of biological
compounds have been developed. The graft copolymer polyethylene-g. co-hydroxyethyl
methacrylate, partially hydrolyzed, has shown to be a very promising support for this
purpose. The more recent work in the preparation and characterization of this copolymer, as
well as the immobilization of a lipase, is reported in this paper. Branches of poly
(hydroxyethyl methacrylate) were grafted onto low density polyethylene by using gamma …
