Tema(s): Recursos en línea: Resumen: Porcine pancreas lipase (PPL)immobilized on porous silica beads and employed successfully for ring-opening polymerization of ethylene isobutyl phosphate (EIBP)was investigated. The factors affecting the activity of the immobilized lipase were studied. A good coupling yield was achieved - 41.88 mg of native lipase /g of porous silica beads. We also studied the thermal properties of this immobilized lipase. The optimum temperature of this immobilized lipase was 708C. After incubation at 908C for 1 h, the activity of immobilized lipase remained above 70
