Abstract: | Summary The ring opening polymerization of 3,9-bismethylene-2, 4, 8, 10-tetraoxa-spiro[5,5]undecane was investigated. It was shown that this bifunctional ketenacetal undergoes a radical homo- and copolymerization forming crosslinked polymers with a high degree of ring opened units. Using other initiators than radicals it is possible to get statements about the electronical state of ketenacetal functions in saturated heterocycles. |
