## Abstract The mechanism of thermal degradation of the polymer obtained by polycondensation of ethyleneurea with formaldehyde was studied in detail using several techniques. On heating the polymer undergoes crystallisation at about 175ยฐC. Upon melting (at 355ยฐC) further condensation of ethyleneure

## Abstract A theory is presented of the way in which the melting of a polymer is manifested in a differential temperature analysis thermogram. An analytical method based on this theory allows a precise determination of both the melting point and the crystalline weight fraction as a function of tem
The thermal degradation in oxygen of a number of fluorine-containing polymers haa been studied by using a weight loss technique. The relative thermal stabilities of the different polymers have been determined and, where possible, the overall activation energy and frequency factors for their breakdow
