Summary The bisketeneimine Ph2C=C=N-C6H4-N=C=CPh2 1 has been used as a crosslinker for carboxyl functional (meth)acrylate copolymers of various molar masses, in which the COOH group is attached to the backbone through spacers of various length. The crosslinking reaction, carried out at various temperatures, was monitored by infrared spectroscopy and by dynamic mechanical analysis. From a modelreaction with nonanoic acid kinetic parameters were calculated. The products poly(meth)acrylate-polyimide networks were characterised by NMR and FTIR spectroscopy. The thermal stability (TGA measurement) was comparable to that of a corresponding polyurethane.
