Abstract
Crystallization of crystalline–amorphous blends of polyethylene terephthalate–polystyrene (PET–PS) with and without the addition of triphenyl phosphate was followed by differential scanning calorimetry. Triphenyl phosphate acts as a nucleating agent. Thermal studies of various PET–PS compositions, crystallized from melt, have shown a marginal decrease in the rate of crystallization and an increase in the percentage of crystallinity of the blends. Triphenyl phosphate was found to have a nucleation-facilitation effect on 1:1 PET–PS blend composition and also has improved the crystallinity of PET in quenched blends.
