Summary A poly(l‐lactide‐co‐caprolactone), P(LL‐co‐CL), 75:25 mol % copolymer was synthesized via the bulk ring‐opening copolymerization of l‐lactide (LL) and ϵ‐caprolactone (CL) at 130 °C for 48 hrs. The P(LL‐co‐CL) copolymer obtained was characterized in terms of its molecular weight (GPC), copolymer composition (1H‐NMR), monomer sequencing (13C‐NMR) and thermal properties (DSC, TGA). For processing,...
Monofilaments of a block terpolymer of l-lactide, ɛ-caprolactone and glycolide have been melt spun for potential use as absorbable surgical sutures. As-spun fibres of the terpolymers produced by melt spinning were elastic, amorphous and isotropic. A two-stage process involving hot drawing was employed to enhance their mechanical properties. WAXS and SAXS results coupled with DSC demonstrated that...
We apply a new X-ray scattering approach to the study of melt-spun filaments of tri-block and random terpolymers prepared from lactide, caprolactone and glycolide. Both terpolymers contain random sequences, in both cases the overall fraction of lactide units is ∼0.7 and 13 C and 1 H NMR shows the lactide sequence length to be ∼9–10. A novel representation of the X-ray fibre pattern...
