Abstract

This invention relates to new and useful melt blend compositions of polyethylene terephthalate and polyethylene isophthalate, and melt blend compositions of polyethylene terephthalate with random copolymers of polyethylene terephthalate and polyethylene isophthalate wherein each polyester contains an interesterification inhibitor, wherein the resulting melt blend composition of polyesters retain the predominant characteristics of the predominant polyester by weight of the melt blend composition. The extruded polymer melt blend compositions have utility as shrink fiber and film, and as adhesives in the form of powdered binders for non-woven fabrics.
