A process for the production of a vinyl polymer terminated with a group having a polymerizable carbon-carbon double bond, which brings about improvement in the stability of quality of the polymer. The invention relates to a process for the production of a vinyl polymer terminated with a group having a polymerizable carbon-carbon double bond which is characterized by adding a stabilized free radical as the polymerization inhibitor. The polymer obtained by the process is protected by virtue of the stabilized free radical added during the production from viscosity increase or gelation caused by polymerization of the terminal group having a polymerizable carbon-carbon double bond.
L'invention porte sur un procédé de production d'un polymère de vinyle terminé par un groupe à double liaison carbone-carbone polymérisable, qui contribue à améliorer la stabilité de la qualité du polymère. Ledit polymère, qui se caractérise par l'adjonction d'un radical libre stabilisé servant d'inhibiteur de polymérisation, est protégé pendant la production, du fait de l'adjonction du radical libre stabilisé, de l'accroissement de viscosité ou de la gélification causés par la polymérisation du groupe terminal à double liaison carbone-carbone polymérisable.
