A Novel Approach to the Preparation of Nanoblends of Poly(2,6‐dimethyl‐1,4‐phenylene oxide)/Polyamide 6

Summary: A novel approach of in situ polymerization and in situ compatibilization was adopted to prepare poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) and polyamide 6 (PA6) nanoblends. Anionic ring‐opening polymerization of ε‐caprolactam was carried out in the presence of PPO, the chain of which bore p‐methoxyphenylpropionate (MPAA), acting as macroactivator to initiate PA6 chain growth from the PPO chain and form a graft copolymer of PPO and PA6 and pure PA6 simultaneously. The nanostructured PA6 dispersed phase in the PPO matrix could be achieved.
