MACROMOLECULAR ARCHITECTURES

The “Macromolecular Architecture” research topic is strongly inspired by the historical scientific background of the team which relies on polymerization using coordination chemistry and polymerizations in dispersed media. Our purpose is to design novel polymer architectures using the combination of several of those chemistries and processes. As a result, it very often involves two or more members of the team, each providing his/her own specific skills to the topic. 

Two of the major current topics are:

A) Olefins polymerization by coordination chemistry (particularly systems based on Catalyzed Chain Growth (CCG) or Coordinative Chain Transfer Polymerization (CCTP)) and end-group modification toward polyethylene-based functional materials. This research originates from the strong expertise gained with time in the polyolefin area on one hand and the recent advent of controlled radical polymerization techniques and efficient polymer conjugation reactions on the other hand. We are trying to combine the best attributes of the polyolefins based materials with properties exhibited by the counterpart (functional/reactive molecules, polar/reactive polymers, surfaces, nanotubes, particles etc ) on which the polyolefin can be anchored.

 

 

B) Controlled/living radical polymerization and emulsion or dispersion processes toward self-stabilized nano-objects with various morphologies

Our systems are based on the use of a water-soluble living polymer precursor that can be chain-extended in water via  processes based on polymerization in dispersed media (emulsion, dispersion, miniemulsion) toward the in-situ formation of amphiphilic block copolymers. The latter self-assemble into various types of nano-objects upon chain growth.
