摘要： The present invention relates to cyclic phosphazenes of general formula (1)
wherein Q is a halogen and/or an aryloxy group, and m is an integer of 3 to 10, which are characterized by being substantially free from linear phosphazenes of general formula (2)
wherein Q is a halogen and/or an aryloxy group, and n is an integer of 1 to 20 and by having an extremely low content of halogen, and which are appropriate to flame retardants for resins; processes for preparing the same; flame retardants containing the same as an active ingredient; resin compositions containing the cyclic phosphazenes; and molded articles therefrom.
