## Abstract Optically active poly(__tert__‐butyloxirane)s of various molecular weights were prepared by polymerization of __R__(–)‐__tert__‐butyloxirane with different initiators or by stereoelective polymerization of the racemic monomer. Using identical conditions of polymerization (initiator, tem
The thermal decomposition of phenyl carbazate results in formation of 4-amino urazole. The same compound is formed in reactions which according to other authors yield p-urazine. This six-membered cyclic isomer could not be prepared. The structure of 4-amino urazole is confirmed by study of infrared
