Abstract:
1. A fluorine-containing allyl ether copolymer consisting essentially of chains of at least two repeating units of the formula: wherein A 2 is an organic group having 1 to 100 carbon atoms, wherein at least one repeating unit is a repeating unit of the formula: wherein A is alkyl or fluoroalkyl groups having 1 to 50 carbon atoms, alkenyl or fluoroalkenyl groups having 2 to 50 carbon atoms, alkynyl or fluoroalkynyl groups having 2 to 50 carbon atoms, alkyl or fluoroalkyl groups having an ether bond and 1 to 60 carbon atoms, alkenyl or fluoroalkenyl groups having an ether bond and 2 to 60 carbon atoms, alkynyl or fluoroalkynyl groups having an ether bond and 2 to 60 carbon atoms, aryl or fluoroaryl groups having 4 to 30 carbon atoms, and at least one repeating unit is a repeating unit of the formula: wherein A 1 is a divalent organic group having 1 to 60 carbon atoms, and Y 1 is —CH 2 OH, —COOH, —COOR 1 in which R 1 is a hydrocarbon group having 1 to 20 carbon atoms, in which R 2 and R 3 are the same or different and a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, —O—CF═CF 2 , —OCO—CZ 3 ═CZ 1 Z 2 in which Z 1 and Z 2 are the same or different and a hydrogen atom or fluorine atom, and Z 3 is a hydrogen atom, a fluorine atom, a chlorine atom or a trifluoromethyl group, an epoxy group, a glycidyl group, a cyano group, a sulfonic acid group or a —SO 3 R′ in which R′ is a monovalent organic group.
