Popis:	The microfine structure of poly(2-methylenetetrahydrofuran) obtained by various cationic catalysts was studied by NMR spectroscopy. Only a quartet was observed for the backbone methylene protons of the ethyl methyl ketone-insoluble polymer, which was found to be crystalline by X-ray analysis. The polymer is suggested to be primarily isotactic in nature.
