Alkylene oxide condensates obtained by reacting ethylene oxide and/or propylene oxide with a monohydric 2,2,6,6-tetramethylpiperidine alcohol or a tetramethylpiperidine glycol are useful for introducing basic groups in synthetic polymers. Examples illustrate preparation of a variety of such alkylene oxide condensates which are particularly useful in polyester filaments for imparting acid-dyeability.
