Copolymers of E-caprolactone and glycolide for melt blown nonwoven applications
Abstract:
Copolymers exhibiting the following combinations of properties, including without limitation, ε-caprolactone in an amount ranging from about 12 to about 70 mole percent, glycolide in an amount ranging from about 30 to about 88 mole percent, crystallinity ranging from about 10 to about 50% as measured by WAXD or about 10 to about 50 J/g as measured by DSC, and an inherent viscosity ranging from about 0.5 to about 1.45 dL/g as measured in a 0.1 g/dl solution of HFIP at 25° C.; a method for melt blowing such copolymers and nonwoven constructs produced therefrom are described herein.
