Abstract: A crystallization process comprising passing a mass of amorphous crystallizäble polymer having a first thickness (ft) through the nip gap of counter-rotating rolls having a nip gap (ng)at an ft:ng ratio of at least 1.2 to crystallize the polymer to a degree of crystallinity of at least 15% and thereby produce a semi-crystalline polymer, and particulating the semi-crystalline polymer. Strain crystallizing a sheet or fiber by using a drafting step to elongate the sheet or fiber is no longer needed. A high degree of crystallinity is imparted almost instantaneously, even in slow to crystallize copolyesters. The process allows one to extrude a thinner crystallizable sheet, substantially retains the dimensiona) width of the sheet as it is passed through the compression rolls, and produces substantially optically clear sheet and pellets. Suitable polymers include polyethylene terephthalate or naphthalate homopolymers or copolymers.

Abstract: Disclosed are blends of aliphatic-aromatic copolyesters with poly(ethylene-co-vinyl acetate) copolymers and shaped articles prepared therefrom. These blends have higher melt strength than the aliphatic-aromatic copolyester alone and exhibit increased melt strength and better processability. In addition, the blends and shaped articles show bio-disintegration and/or biodegradability in a composting environment.
