AB - The synthesis of poly(ϵ‐caprolactone‐co‐ϵ‐caprolactam) copolymers using reactive extrusion is reported. The copolymers are prepared by anionic ring‐opening polymerization of ϵ‐caprolactam in polycaprolactone melt in a twin‐screw microcompounder using masterbatches of sodium caprolactamate and hexamethylene‐1,6‐dicarbamoylcaprolactam in ϵ‐caprolactam as initiator and activator, respectively. The monomer conversion is found to be almost quantitative. The extrudates possess polyester backbones with integrated short polyamide fragments, forming co‐existing polyamide and polyester crystals. The polyester crystallinity index is quite low and rather constant, whereas the content of the polyamide α‐ and γ‐phases varies with the copolymer composition and initiator/activator concentration.
