As a means of developing high-performance engineering thermoplastic elastomers (TPEs) as well as reducing environmental pollution caused by plastic waste, α,ω-hydroxyl terminated polycaprolactone (PCL) polyols with molecular weights (MWs) of 1,000–4,200 g mol−1 and Polydispersity index (PDI) of 1.30–1.88 have been synthesized by ring-opening polymerization (ROP) of ε-caprolactone using a heterogeneous double metal cyanide (DMC) catalyst. A series of poly(ester–ester)s TPE (TPEE) were produced using the PCL polyol and poly(butylene terephthalate) segments. The resultant polymers were characterized by spectroscopic, chromatographic, thermal, and mechanical analyses. The biodegradability was also evaluated according to ISO-14852 standard. The TPEE showed superior mechanical properties and biodegradability to conventional polytetramethylene ether glycol (PTMEG) based TPE due to significant differences in crystallinity and microphase separation behaviors. The introduction of biodegradable PCL demonstrates significant potential for making high-performance TPEs reducing potential environmental concerns.
