SPHEROIDAL POLYESTER POLYMER PARTICLES |
摘要 |
Spheroidal polyester polymer particles, as well as preforms and stretch blow molded bottles made from the spheroidal particles, are provided which have; A) an It.V. of at leas; 0.72 dL/g, and either B) at least two melting peaks (on a DSC first heating scan), wherein one of said at least two melting peaks is is a low peak melting point having a peak temperature within a range of 140 °C to 320 °C and having a melting endotherm area of at least the absolute value of 1 J/g, or C) a low degree of crystallinity within a range of at least 23% and a maximum degree of crystallinity T emax defined by the equation: T emax - 50% - CA - OH where C A is the total mole % of all carboxylie acid residues other than terephthalic acid residues, based on 100 mole % of carboxylic acid residues in the polyester polymer, and OH is the total mole % of hydroxyl functional compound residues other than ethylene glycol residues. based on 100 mole % of the hydroxyl functional compounds residues; of both B) and C); and optionally but : preferably D) 10 ppm or less of residual acetaldehyde. |
