Multiple melting behavior of Nylon 1010 has been investigated by using DSC instrument. Effect of partial scanning

partial scanning and annealing

heating rate

cooling rate and successive annealing at lower temperature on the melting curve was studied. Experimental results indicate that the sample undergoes a process of continuous melting and recrystallization during DSC scanning. Nylon 1010 contains a distribution of crystallites of different degrees of perfection which is strongly dependent on its previous thermal history. From the structural reorganization point of view

the orign of double and multiple peaks on the melting curve is explained.
