Abstract

Abstract: The melting of sphcrulitcs of nylon 1010 formed in isothermal crystallization has been studied by hot stage polarizing microscopy. The melting temperature (T_m) of the ringed positive spherulitcs was 182℃; that of the non-ringed positive spherulites, the mixed nonringed spherulitcs,the darker and brighter non ringed negative sphcrulitcs,were 203℃,202～205℃, and 204～210℃, respectively. Thus, the equilibrium melting temperature was 215℃ by extrapolating.

Key words: Nylon 1010, spherulite, melting, equilibrium melting temperature, polarizing microscopy
