D. Cayuela et J. Gacen, CONTRIBUTION OF THE SECONDARY CRYSTALLIZATION TO THE OVERALL CRYSTALLINITY OF HEATSET POLYESTER, Journal of thermal analysis, 41(6), 1994, pp. 1599-1605
The crystallinity of poly(ethyleneterephthalate) has been determined b
y differential scanning calorimetry and by density. The results obtain
ed by calorimetry show that the increment in the crystallinity due to
the heatsetting treatment is produced by the increase of the crystalli
nity corresponding to the premelting endothermic peak.
