Abstract

Abstract Homo- and Copolymers of monomeric perfluoralkylalkylmonocarboxylic acid esters are provided which esters are derived from acyclic aliphatic epoxides. These esters contain at least one perfluoroalkyl radical with 4 to 14 carbon atoms which is bonded over an alkylene group with 1 to 10 carbon atoms to a carboxyl group, which in turn is bonded in an esterlike manner to an acyclic radical. This radical contains in the 2-position to the ester bridge an optionally etherified or esterified hydroxyl group; said radical is bonded via an ester, ether or carbamate bridge to an alkenyl group with 2 to 3 carbon atoms which is optionally linked via a second ester, ether or carbamate bridge to an acyclic radical which in turn may be bonded via an ester bridge and an alkylene group to a perfluoroalkyl radical. The homo- and copolymers with other polymerisable products are used to achieve oleophobic furnishes on porous or non-porous substrates, especially on fibrous materials, such as textiles and papers.
