Title
(EN) PREPARATION OF CYANO-CONTAINING PERFLUOROPOLYMERS HAVING IODINE CURESITES
(FR) PREPARATION DE CYANO PERFLUOROPOLYMERES CONTENANT DES SITES DE DURCISSEMENT IODIQUES
Abstract
(EN)
In the preparation of perfluoropolymers by the interpolymerization of tetrafluoroethylene, perfluoro (alkyl vinyl) ether and cyano-cure site monomer, the improvement of incorporating iodo moieties by the reaction of iodo-compounds of the formula RIn, in which R is a hydrocarbon or halocarbon radical of 1 to 8 carbon atoms and n is 1 or 2.
(FR)
Afin d'améliorer la préparation de perfluoropolymères par interpolymérisation de tétrafluoroéthylène, de perfluoro (alkylvinyl) éther et de monomères à site de durcissement cyanique, on incorpore des moitiés iodiques par réaction de composés iodiques ayant la formule RIn, dans laquelle R est un radical hydrocarbure ou halocarbure ayant entre 1 et 8 atomes de carbone et n est égal à 1 ou 2.
