Abstract: This study assesses the use of immobilized lipase catalyst N435 during reactive extrusion (REX) versus magnetically stirred bulk and solution reaction conditions for the copolymerization of ε-caprolactone with ω-pentadecalactone (CL/PDL 1:1 molar). N435-catalyzed REX for reaction… read more here.

Abstract: The combined interaction of 2,3,6,7-tetrahydro-5H-thiazolo[3,2-a] pyrimidine (ITU) as the organocatalytic nucleophile with YCl3 as Lewis acid cocatalyst, generating ITU/YCl3, was employed for homo- and copolymerization of e-caprolactone (CL) with δ-valerolactone (VL). Poly(caprolactone) (PCL) and poly(caprolactone)–poly(ethylene… read more here.

DOI: 10.1039/d1nj01946e
Abstract: Metal organic frameworks (MOFs) are not much investigated as catalysts in copolymer formation with cyclic esters. Herein, we report the ring-opening copolymerization of e-caprolactone (CL) with δ-valerolactone (VL) using a recoverable and reusable Ti-metal based… read more here.
