A series of approximately 50:50 mol % poly(L-lactide-co-ε-caprolactone) copolymers were synthesized by bulk copolymerization of L-lactide (LL) and ε-caprolactone (CL) using stannous octoate (Sn(Oct) 2 ) and diethylene glycol (DEG) as the initiating system. The resulting P(LL-co-CL) copolymers were characterized by various analytical techniques including dilute-solution viscometry, GPC, H/C NMR ...

The paper explored the catalytic activity of a cell debris self-immobilized thermophilic lipase for polyester synthesis, using the ring-opening polymerization of ε-caprolactone as model. Effects of biocatalyst concentration, temperature, and reaction medium on monomer conversion and product molecular weight were systematically evaluated. The biocatalyst displayed high catalytic activity at high...

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

Patterned coatings based on biodegradable crosslinked poly(ester/carbonate) have been prepared by photo-induced ring-opening polymerization of a liquid bifunctional trimethylene carbonate-based monomer using poly(ε-caprolactone) triol as initiator and guanidine superbase photogenerator activated irradiation at 385 nm. The influence various parameters gel time such components molar ratios, or re...
