To avoid the harmful effects of metallic residues in poly(1,4-dioxan-2-one) (PPDO) for medical applications, the enzymatic polymerization of 1,4-dioxan-2-one (PDO) was carried out at 60 Β°C for 15 h with 5 wt % immobilized lipase CA. The lipase CA, derived from Candida antarctica, exhibited especiall
Lipase-catalyzed ring-opening bulk polymerizations of 3(S)-isopropylmorpholine-2,5-dione (IPMD) were investigated. Selected commercial lipases were screened as catalysts for IPMD polymerization at 100 8C. Polymerizations catalyzed with lipases PPL, PS, and CR result in IPMD conversions of about 50%,
