Abstract

Spherulites of double crystallizable block copolymers grafted to a polyester backbone are shown as imaged by polarized optical microscopy. As presented by Dirk Pfefferkorn, Martin Pulst, Toufik Naolou, Karsten Busse, Jens Balko, and Jörg Kressler on page 1581, the diblock copolymers are formed by poly(ϵ-caprolactone) and poly(ethylene oxide) and the backbone by the biodegradable poly(glycerol adipate), which is synthesized by enzymatic polycondensation.
