The acid catalysed reaction of formaldehyde with activated aromatics (e.g. phenol) to form oligomers is well known. The feasibility of using this approach to prepare maleimide functionalized oligomers has been explored by undertaking model compound studies with N-(4-phenoxy)-phenylmaleimide (PPM), N-(2-methoxy)-phenylmaleimide (MPM) and N-phenylmaleimide (PM). Under common reaction conditions PPM readily forms a series of discrete methylene bridged oligomer structures, MPM reacts relatively slowly to give a dimer only whilst PM does not react. Thermal analysis of the cured PPM oligomers shows that they possess excellent thermal properties.
