摘要： Disclosed are mixtures comprising at least two phosphine oxides of formula (I) wherein R1 is a monovalent organic group, R2, R3, R4 and R5 independently of one another are hydrogen, alkyl groups having between one and eight carbon atoms or aryl groups having between six and eighteen carbon atoms, n and m independently of one another are integers between 0 and 10. These phosphine oxides can be used to manufacture flame-retardant polymers.
