Hydrophilic oil-repellent polymers

Abstract

Provided is a hydrophilic oil-repellent polymer which exhibits high antifouling properties in a wet environment by having high oil repellency in water, and which has excellent shape transfer properties during molding. A polymer comprising a structural unit A derived from ethylene and / or propylene, a structural unit B of the following formula (1) and a structural unit C of the following formula (2). In formula (1), L16 represents-(CH2) n-(Rf2O) p-(Rf3) h-(Si (Rf4) 2O) g-Si (Rf1) 3, Rf1 represents a hydrogen atom or a C1-15 alkyl group, Rf2 and Rf3 represent a C1-15 alkylene group, Rf4 represents a hydrogen atom or a substituted or unsubstituted C1-15 alkyl group or a substituted or unsubstituted C6-20 aryl group, n represents an integer of 0-10, p represents an integer of 0-15, h represents an integer of 0-15, and g represents an integer of 1-1000. In formula (2), L26 represents-(CH2) m-(Rr2O) q-Rr1, Rr1 represents a hydrogen atom or a C1-15 alkyl group or a C1-20 aryl group, Rr2 represents a C1-15 alkylene group, q represents an integer of 1-1000000, and m represents an integer of 0-10.
