The structure of polymer obtained by gamma -radiationinduced solid- state polymerization was examined by x-ray diffraction analysis. The polymers of 3,3-bischloromethylcycloxabutane, trioxane, and tetraoxane were shown to have an oriented mosaic structure of twin crystallites, of which two polymers of oxymethylene were in helical configuration. The polymer of BETA -propiolactone was not in the twin crystal form. Two kinds of polymers obtained from BETA - propiolactone and 3,3-bischloromethylcycloxabutane were found to be in planar zigzag configuration. (auth)
