An object of the present invention is to provide a mixture of cyclophosphazenes suitably substituted with phenoxy having a polymerizable functional group, such as allyl, on the phenyl ring and a production method for the mixture. The invention relates to a mixture of cyclophosphazene compounds that each contain a plurality of constituent units linked to each other, each constituent unit being represented by formula (I):
wherein R1 and R2 are identical or different and represent C1-4 alkyl or the like, the mixture containing cyclophosphazene compounds in which 3, 4, and 5 constituent units represented by formula (I) are linked, wherein the cyclophosphazene compound containing 3 linked constituent units is cyclophosphazene compound (I-A) with a specific structure, compound (I-A) includes cyclophosphazene compounds (I-A2) and (I-A3) having a specific structure, and compounds (I-A2) and (I-A3) are present in an amount of 80 wt % or more in total in cyclophosphazene compound (I-A).
本发明的目的是提供一种被苯氧基适当取代的环膦烯混合物,该混合物的苯环上具有可聚合的官能团,如烯丙基,以及该混合物的生产方法。本发明涉及一种环膦唑化合物的混合物,每种环膦唑化合物都含有多个彼此相连的组成单元,每个组成单元由式(I)表示:
其中 R1 和 R2 相同或不同,代表 C1-4 烷基或类似物,该混合物含有 3、4 和 5 个由式(I)代表的组成单元相连的环膦烯化合物,其中含有 3 个相连组成单元的环膦烯化合物是具有特定结构的环膦烯化合物(I-A)、化合物(I-A)包括具有特定结构的环膦唑化合物(I-A2)和(I-A3),且化合物(I-A2)和(I-A3)在环膦唑化合物(I-A)中的总含量为 80 wt % 或以上。
