Effect of molar ratio on thermal mass loss kinetics of poly(ɛ-caprolactone-b-propylene adipate) copolymers

► Thermal decomposition behaviour of PCL-b-PPAd block copolymers was estimated. ► The prepared copolymers have higher thermal stability than neat polymers. ► In copolymers the evaporation of PPAd short blocks and formed ɛ-CL is delayed. ► This is because copolymers degrade with a different mechanism than neat polymers.
