The characteristics of pure - and -form of the cyclic dimer (1,8-diazacyclotetradecane-2,9-dione) were systematically and integrally investigated during this study. The results showed that the -form could dissolve and rapidly transform into the -form in methanol, and in caprolactam solution at a low...
