Abstract: Copolymers of (A) perfluoroalkylethyl acrylate CnF2n+1CH2CH2OCOCH=CH2 (n=6-12) (B) higher alkyl acryinto CmH2m+1OCOCH=CH2 (m=10-16) (C) vinylideno chloride CH2=CC12 (D) acroylbutylurethane CH2=CH-CONHCOOC4H9 at the weight ratio of 1(A) : 0.22-0.39(B) : 0.45-0.85(C) : 0.01-0.15(D) n being 6, 8, 10, 12 or 14 and m being a number from 10 to 16. They are prepared by conventional methods for preparing copolymers and are used as oil - and water repellants for porous materials, especially textile materials.
