Non-fluorinated copolymers, water-repellent and oil-repellent compositions, and articles

Abstract

This disclosure discloses a non-fluorinated copolymer having units m1 mainly composed of X1-A1-B1 and units m2 mainly composed of halogenated olefins, wherein the ratio of units m2 mainly composed of halogenated olefins is 3 to 35% by mass of the total structural units. X1 is a monovalent polymerizable reactive group, A1 is a divalent organic group, and B1 is a monovalent organic group having at least one trialkylsilyl group.
