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): n n n n n n n n n n wherein R 1 and R 2 are identical or different and represent C 1-4 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-A 2 ) and (I-A 3 ) having a specific structure, and compounds (I-A 2 ) and (I-A 3 ) are present in an amount of 80 wt % or more in total in cyclophosphazene compound (I-A). |
