The invention relates to a polymer having the structure
and mixtures thereof wherein R is a perhalogenated aromatic or cyclo aliphatic radical containing from 6 to 7 carbon atoms in the cyclic structure; R¹ is hydroxy or C₁ to C₁₀ alkoxy; R² is hydrogen or C₁ to C₁₀ alkyl; EO represents the radical -CH₂CH₂O-; PO represents the radical
m is an integer having a value of from 6 to 20; and x, y, z, x′, y′ and z′ each represent an integer having a value of from 0 to 50 with the proviso that sums of x + y + z and of x′ + y′ + z′ are greater than 5.
The application is also directed to the preparation and use of the above polymer, e.g. for soil release or flame retardancy.
本发明涉及一种具有以下结构的聚合物
