ABSTRACT:
A melt-blended composition containing at least two kinds of hydrolyzed ethylene-vinyl acetate copolymers having a different ethylene content from each other within the range of 20 to 55% by mole, a degree of hydrolysis in vinyl acetate component of at least 80% by mole and a specific melt tension as defined herein, the hydrolyzed copolymers included in the largest amount and the second largest amount among the hydrolyzed copolymers constituting the composition having a specific relationship with each other in weight ratio and ethylene content and the fusion curve of the composition indicating substantially single peak. The composition has an improved melt-moldability, and provides molded articles having remarkably reduced fish eyes and uniform thickness or excellent dimensional stability.
