Abstract:
A fluorocopolymer capable of exhibiting excellent water and oil resistance even with its perfluoroalkyl group being a short chain, and a water and oil proofing composition containing it, are provided.A water and oil proofing composition containing a fluorocopolymer (A) comprising from 40 to 98 mass % of polymerized units (a′) having a C1-6 perfluoroalkyl group, from 1 to 50 mass % of polymerized units (b′) having an alkylene oxide and from 1 to 10 mass % of polymerized units (c′) based on a monomer represented by CH2═C(COOH)-Q-COOH (wherein Q is a C1-4 alkylene group, etc.).
