This invention relates to novel multifunctional oxetanes, i.e., compounds having multiple oxetane groups, which are useful as initiators in the preparation of star polymers and polymer cascades containing energetic groups. In addition, this invention relates to a process for the preparation of star polymers and polymer cascades, whereby novel multifunctional oxetanes act as initiators in the formation of theses polymers. The reaction of these initiators with various propagating, high-energy oxetanes, such as 3,3-bis-(azidomethyl)oxetane (BAMO) and 3-nitratomethyl-3-methyloxetane (NMMO), gives star polymers with varying molecular weights and functionalities. The star polymers and polymer cascades of the present invention are useful as binders in high-energy formulations.
