Abstract
On the occasion of the RSEQ Award for Distinguished Career, the author describes her contribution to polymer research and its evolution throughout her more than 45 years of profession in which she has combined scientific and technological challenges. The work includes the study of the thermal degradation of polyvinyl chloride (PVC), the transition to modification reactions in solution, in the molten state (extruder) and the surface modification reactions of some polymers. It ends with her most current contributions in the field of nanoscience and nanotechnology.
