Abstract
Abstract Compounds containing (a) a fluoroaliphaticsulfonamido moiety, and (b) a moiety containing (1) at least two oxirane groups, (2) at least two non-terminal N-β-hydroxyalkylene groups, or (3) at least one oxirane group and at least one non-terminal N-β-hydroxyalkylene group. The compound is capable of being cured with a curing agent to give a cured product having excellent water resistance and oil resistance.
