Abstract:
(EN) A fluoropolymer having fluoropolyether linkages, at least two ester linkages, and hydrolyzable functional groups is represented by chemical structure (I), as shown in claim 1. With respect to chemical structure (I), m is a number from 1 to 4 and n is a number from 10 to 60, each R1 is independently fluorine or CF3, R2 is an alkylene group, R3 is an alkylene group in which one or more hydrogens of the alkylene group are optionally substituted with fluorine, R4 is an alkyl group in which one or more hydrogens of the alkyl group are substituted with fluorine, R5 is an alkylene group in which at least one hydrogen of the alkylene group is substituted with a group comprising CF3, CF2CH, or a hydrolyzable silyl group, and Z is a group represented by chemical structure (II), as shown in claim 1. Methods of preparing the fluoropolymer and coating compositions containing the fluoropolymer are also included.
(FR) L'invention concerne un fluoropolymère comportant des liaisons fluoropolyéther, au moins deux liaisons ester et des groupes fonctionnels hydrolysables qui est représenté par la structure chimique (I), comme le montre la revendication 1. En ce qui concerne la structure chimique (I), m représente un nombre de 1 à 4 et n représente un nombre de 10 à 60, chaque R1 est indépendamment un fluor ou un CF3, R2 représente un groupe alkylène, R3 représente un groupe alkylène dans lequel un ou plusieurs hydrogènes du groupe alkylène sont éventuellement substitués par des fluors, R4 représente un groupe alkyle dans lequel un ou plusieurs hydrogènes du groupe alkyle sont substitués par des fluors, R5 représente un groupe alkylène dans lequel au moins un hydrogène du groupe alkylène est substitué par un groupe comprenant un CF3, un CF2CH, ou un groupe silyle hydrolysable, et Z représente un groupe représenté par la structure chimique (II), comme le montre la revendication 1. L'invention concerne également des procédés du fluoropolymère et des compositions de revêtement contenant le fluoropolymère.
