Functionalized poly(ε‐caprolactone) and copolymers with ethylene oxide through heterogeneous anionic coordinated polymerization. NMR characterization and crystallinity

Abstract

Abstract Functionalized poly(ε‐caprolactone)s have been easily prepared by using a new heterogeneous catalytic system consisting of aluminium alcoholate supported on porous silica and the corresponding alcohol in excess. The polymers have been fully characterized by 1 H and 13 C NMR spectroscopy. Oligo(caprolactone‐ co ‐ethylene oxide)s have been synthesized by the same catalytic system. The diad comonomer distribution as obtained by 1 H NMR suggests a blocky structure. In addition, low degrees of crystallization have been determined by means of DSC.
