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)
with an epihalohydrin of the formula (VI)
in 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.
本发明描述了一种制备增效稳定剂混合物的工艺,该混合物包括根据权利要求 1 所述通式(I)、(II)和(III)的组分,其特征在于式(V)的化合物与式(VI)的表卤素发生反应
与式 (VI) 的表卤代烃反应
在相转移催化剂和相对于化合物(V)摩尔量 4 至 20 倍的碱金属氢氧化物存在下,在 20 至 220 摄氏度下进行反应,除去过量的表卤代醇并进行相分离,然后在 100 至 240 摄氏度下进行聚合。
