“…These samples were selected as representative of the low , ' V Thus it is seen t h a t the increase in crystallite size is not appreciable in the range of T, = 105 "C t o T, = 150 "C whereas in the range of T, = 150 "C to T, = 235 "C the crystallite size increase is appreciable. KILIAN et al 2) measured the percentage crystallinity of P E T as a function of Tc, and found t h a t above T, = 145°C the crystallinity increases rapidly and reaches a maximum value a t T, = 240 "C. Our observation of the growth of crystallite size as a function of Tc agrees with the above result.…”

“…For the density of the noncrystalline phase Qa in PET different values in the range between 1.333 and 1.337 Mg/m 3 are reported in the literature [16][17][18]. According to the equations (1)- (3) with 4 unknown quantities the volume ratio of the crystalline regions and the microvoids can be calculated dependent upon the density of the noncrystalline phase.…”
