A polymer comprising fluoroalkyl group has a structure in which one or two parts of the fluoroalkyl group at the one or both ends of the molecule are linked to a part of alkylene groups or alkylene groups substituted with halogen, a part of alkylene group substituted with functional groups, such as halogen, cyano group, alkylsulfonic acid group, amidoalkylsulfonic acid group, carboxylic acid group, carboxyl group, oxycarbonyl group, ether group, epoxy group and the like, and/or a part of silicone group. A method of preparation of the polymer comprising fluoroalkyl group contains reaction of a fluoroalkanoyl peroxide with a monomer comprising the functional group or a monomer comprising silicone group. A surface active agent comprises fluoroalkyl group and caroxylic acid salt group. A surface treatment agent comprises the polymer comprising fluoroalkyl group, hydrolysis products thereof, hydrolytic condensation products thereof, and mixtures thereof. A coating composition comprises the polymer comprising fluoroalkyl group. The polymer comprising fluoroalkyl group has excellent water repellency, oil repellency and weatherability because the fluoroalkyl group is introduced into the molecule through carbon-carbon linkage.
