Abstract

Procedure for obtaining halogenous polyalkylene glycol yl ether, containing hydroxyl groups, characterized in that polyalkylene glycol yl ethers of general formula **(See formula)** where R1 represents hydrogen, a C1 to C4-alkyl, methoxy, ethoxy, fenoici, chloro or bromo group, R2 represents hydrogen, a methyl or ethyl group, n represents an integer from 1-20 and m represents 1 or 2 and R, in the case that m is equal to 1 or 2, it means hydrogen or, in the case that it is 1 it means a residue of general formula **(See formula)** Where R3 represents a methylene, methylmethylene, dimethylmethylene, sulfone or ether group (p = 1) and p represents 0 or 1, elemental chlorine or bromine or a mixture of both elements is reacted.
