Abstract: A systematic study of isothermal crystallization of P4MP from melt has been carried out using differential scanning calorimeter (DSC). The DSC curve from melting of the sample crystallized under different condition show two melting peaks (endotherms). This phenomenon has been investigated in detail and it has been shown that the one peak I is due to the melting of the isothermally crystallized fraction while the other melting peak namely peak II Is due to the melting of fraction which recrystallized or reorganized on heating.
