Chemical synthesis, polymers ring-opening metathesis

Unsaturated polymers can be produced by means of ring-opening metathesis polymerization (ROMP) of cyclic alkenes. These unique polymers can also be produced via intermolecular Acyclic Diene Metathesis (ADMET). Dienes can also react intramolecularly via Ring Closing Metathesis (RCM) to afford cyclic products. RCM is often applied to synthesis of compounds for fine chemical and pharmaceutical application. Generic examples of these reactions are shown in Figure 2. 

Abstract The presented paper is a summary of our results on synthesis and polymerization of silyl-containing norbomenes and norbomadienes via ring-opening metathesis polymerization (ROMP) and addition processes as well as ring-opening polymerization (ROP) of silacyclobutanes and disilacyclobutanes. The synthesis of heterochain and carbochain polymer families with regularly varied substituents at Si atom and various number and location Si(CH3)3-substituents has been realized. Systematic study of gas transport parameters of polycarbosilanes series of different classes allowed us to find out real eorrelations between features of chemical polymer structure and its gas separation eharacteristics. 

Dr. St phane Carlotti has been an assodate professor at the University of Bordeaux 1 since 2007. He completed his PhD course in the field of polymer sdence in 1998 at the University of Montpellier. After a postdoctoral stay at the Loker Hydrocarbon Research Institute (University of Southern California, Los Angeles, CA, USA), supervised by Pr. T. Hogen-Esch, he joined the Laboratoire de Chimie des Polym res Organiques (LCPO) in 1999 at the University of Bordeaux 1 as assistant professor. He worked mainly on the synthesis of polymers and copolymers with controlled architecture. He studied the living anionic polymerizations of ethylenic monomers in bulk at high temperature and cydic ethers by an activated mechanism. Other interests are in the fields of ring-opening metathesis polymerization and chemical modification of polymers.
