Synthese,caracterisation et reactivite de polymeres porteurs de fonctions chloroformiates

Chemical modification of low molecular weight polymers having functional groups along the chain, can lead to new macromolecular compounds which direct synthesis cannot be studied by classical polymerization ways. Synthesis of polymers possessing chloroformate groups has been obtained by a double modification reaction of polydienes backbones. Reactivity of new functions has been used for fixation of various organic compounds on the macromolecular chain. On the resulting polymers, the organic products are linked by carbonate, urethane or thiolcarbonate bounds varying with the nature of starting molecules: alcohol, amine or thiol which has reacted on the chloroformate groups.
