## Abstract For the triblock copolymer of ε‐caprolactone, trimethylene carbonate, and L‐lactide, where L‐lactide blocks form the two ends, there is a range of compositions over which elastomeric behavior is obtained. Within this composition range, these polymers show good creep and recovery at ambi
Copolymers of c-caprolactone and L-lactide (c-CL/L-LA) and c-caprolactone and DL-lactide (c-CL/DL-LA) were synthesized with compositions 80/20,60/40, and 40/60 (wt % in feed). The polymerization temperature was 140°C and Sn(I1)octoate was used as a catalyst. The effect of the comonomer ratio on the
