Polymérisation du chloroformiate de vinyle et de ses dérivés

The free-radical polymerization of vinyl chloroformate has been studied in methylene chloride at 35 °C using dicyclohexyl peroxydicarbonate as initiator. Kinetic measurements performed by dilatometry under high vacuum have shown that the reaction order in monomer is equal to one whereas that in catalyst is equal to 0.5.New polymers have been prepared either by free-radical polymerization of monomers derived from vinyl chloroformate or by chemical modification of poly(vinyl chloroformate) with amines, alcohols, thiols, carboxylic acids, KCN … using phase transfer catalysis. The structure of these polymers as well as their thermal behaviour have been studied.
