Crystallization and melting of nylon 610

摘要

Differential scanning calorimetry was used to study the crystallization and melting of nylon 610. for nylon 610 crystallized from the melt state (260 deg. c), the overall rate of bulk crystallization can be described by a simple Avrami equation with Avrami exponent n≈2, independent of crystallization temperature. With the experimentally obtained T~0 _m (235 deg. C ～255 deg. C) of nylon 610, the fold surface free energy σ_e was determined to be 35～38 erg/cm~2. The erects of annealing temperature and time on the melting of quenched nylon 610 were also investigated.
