Abstract
The present invention relates to a process for the preparation, of thermoprecipitating affinity polymers useful in the enhanced recovery of enzymes. The process comprises polymerising a monomer comprising a spacer and a co-monomer with a polymerisation initiator and a polymerisation accelerator at ambient temperature and pressure for a period ranging between 2 to 24 hours to obtain a polymer and then linking an inhibitor to pendant carboxyl groups of the spacers in the polymer to obtain an affinity polymer.
