摘要：
A process for producing a dilatation balloon by extruding a multiblock copolymer composition to form an extrudate comprising phase-separated glassy, rubber, and semicrystalline microdomains that are macroscopically ordered in a perpendicular alignment. The balloon formed by the process demonstrates, during inflation, a true stress vs. nominal strain response curve comprising a first zone representative of a low modulus balloon, a second zone representative of a high strength balloon, and a sharp transition from the first zone to the second zone.
