## Abstract Anionic polymerization of ε‐caprolactam was performed in the presence of only 5 wt % of aromatic polyimides having five‐ and six‐membered imide cycles and bearing hexafluoroisopropylidene, ether, fluorene, siloxane, phthalide, or SO~3~H groups, both in the polymer backbone and as side

The N-sodiocaprolactam-catalysed anionic polymerisation of e-caprolactam is activated by e-caprolactone which itself acts as a comonomer, yielding copolyesteramides. At lower temperatures and lower catalyst concentrations, copolymerisation of the lactone is favoured over that of lactam; higher tempe
Almtraet--The crystalline character of anionic copolymers of c-caprolactam with ~-caprolactone and of some alternatingly-sequenced analogues has been studied and investigations made of the mechanical and dynamic mechanical properties of the anionic copolymers. The anionic copolymers are crystalline
