| abstract |
The present invention describes a process for preparing a synergistic stabilizer mixture comprising the components of the general formulae (I), (II) and (III) in accordance with claim 1, characterized by the reaction of compounds of the formula (V) n n nwith an epihalohydrin of the formula (VI) n nin the presence of a phase transfer catalyst and from 4 to 20 times the molar amount of an alkali metal hydroxide, relative to compound (V), at from 20 to 220° C. Removal of the excess epihalohydrin and phase separation are followed by polymerization at from 100 to 240° C. |
