Investigation of Ring-Opening Polymerization of 2-Phenoxymethyl-1,4,6-trioxa-spiro[4,4]-nonanUnder the conditions of a radical induced cationic ringopening-polymerization the spiro ortho ester 1b can be polymerized with diphenyliodoniumtetrafluorborat/benzpinacol (1:1). The optimal initiator concentration is 2-2.5 mol-% Ph2I+BF4-. The average molecular weight is 6000, Tg = -4°C. Polymerization of 1b in presence of BF3 · Et2O produced identical results. The structure of polymer 2b was indicated by its analysis as well as its infrared spectra.
