Abstract: To provide a polymer which can provide a water- and oil-proof paper with excellent water and oil resistance. A polymer comprising the following units a, and at least the following units b among the following units b and the following units c, wherein the ratio of units a to all the units in the polymer is from 28 to 70 mol %, the total ratio of units b and units c to all the units in the polymer is from 30 to 72 mol %, and the ratio of units b to the sum of units b and units c is at least 45 mol %: units a: units represented by —(CH2—CHRf)— (wherein Rf is a C1-s perfluoroalkyl group), units b: units represented by —(CH2—CH(OH))—, units c: units represented by —(CH2—CH(OC(═O)R))— (wherein R is a C1-4 alkyl group).
