Abstract

A water and oil repellent composition comprising a compound of the following formula (1) and a thermoplastic polymer, as essential components:

where the symbols in the formula (1) have the following meanings:

R^f: a C_1-20 polyfluoroalkyl group,

X: (CH₂)_m, wherein m is an integer of from 1 to 10,

A, A¹, A²: each independently, O, S or N(Z³), wherein Z³ is a hydrogen atom or an alkyl group,

Z¹: an octadecyl group,

Z²: an alkyl group, or an alkyl group having at least one hydrogen atom substituted,

W: a trivalent organic group, and

a, b: each independently, 1 or 2, provided that a+b is 2 or 3.
