A polyester composition having an L* value, and a reheat index which increases between 0.95 and 1.15 with an increasing amount of a reheat additive present in the polyester composition is disclosed. A slope of a curve representing increasing amounts of said additive plotted against L* measurements on a y axis and the reheat index on an x axis is ¦80¦ or less, as measured by at least three data points anywhere between 0.95 and 1.15 with respect to reheat index values using intervals of at least 0.03 units and as measured using three stacked discs each having a thickness of 1.7mm (67 mils). A thermoplastic composition comprising a thermoplastic polymer continuous phase solid at 25°C and 1 atm and an additive reducing a coefficient of static friction of the composition relative to a composition without the additive is disclosed. The composition has a coefficient of static friction of 0.2 as measured at a point within an additive range of 50 ppm to 250 ppm relative to the weight of the thermoplastic continuous phase.
