POLY(GLYCOLIC ACID)/POLY(OXYETHYLENE)TRIBLOCK COPOLYMERS AND METHOD OF MANUFACTURING THE SAME ABSTRACT OF THE DISCLOSURE Poly(glycolic acid)poly(oxyethylene) ABA triblock co- polymers having the following formula: Image wherein R represents an alkylene, x is about 37.5 to 47.5, and y is about 5 to 25, weight percent. The copolymers are useful for manufacturing fibers possessing a sufficiently low modulus of elasticity to permit their use as absorbable sutures having the requisite flexibility for use in monofilament form. A process of preparation involves purifying the hydroxyl-ended poly(oxyalkyl- ene) and allowing it to react with glycolide to produce an ABA triblock copolymer of extrusion grade in which A represents a polyglycolic acid block and B represents a poly(oxyalkylene) block.
