Spheroidal polyester polymer particles

A bulk comprising polyester polymer spheroids having:

• A) an average It.V. of at least 0.72 dL/g, and either
• B) melting points characterized by:
• a. at least two melting peaks, wherein one of said at least two melting peaks when measured on a first DSC scan is a low peak melting point having a peak temperature within a range of 140° C. to 220° C. and having a melting endotherm area of at least the absolute value of 1 J/g, or
• b. having one or more melting points which, when measured on a DSC first heating scan, has a heating curve departing from a baseline in the endothermic direction at a temperature of less than or equal to 200° C., or
• C) a low degree of crystallinity within a range of at least 20% and a maximum degree of crystallinity Tcmax defined by the equation:
• Tcmax=50%−CA−OH
• where CA is the total mole % of all carboxylic 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;
• or
• both B) and C).
