## Abstract Enzymatic ring‐opening polymerization of a 6‐membered cyclic carbonate, 1,3‐dioxan‐2‐one, was investigated by using lipase as catalyst in bulk. Supported lipase derived from __Candida antarctica__ catalyzed the polymerization to give the corresponding aliphatic polycarbonate. Unchanged
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 °C for 15 h with 5 wt % immobilized lipase CA. The lipase CA, derived from Candida antarctica, exhibited especiall
