Abstract
This invention relates to an improved polyester composition that has a wide temperature range of crystallization. The composition comprises a polyester and a chemically reacting crystallization modifier having the following formula: EQU H.sub.2 N--R.sup.1 --O--(R.sup.2 --O).sub.x --R.sup.3 --NH.sub.2 wherein PA1 R.sup.1 and R.sup.3 are independently selected from the group consisting of alkylene units having from about 2 to about 6 carbon atoms; PA1 R.sup.2 is a hydrocarbon radical of 2-6 carbon atoms; and PA1 x is from 1 to 100.
