Abstract
The invention provides pellets of a saponified ethylene-vinyl acetate copolymer which are excellent in feedability, cause little fluctuation of extruder torque or discharge during molding, and yield shaped articles with high dimensional accuracy such as the high accuracy of form and thickness. The pellets of the invention are such that the differential curve representing the magnitude of change in the cumulative pore volume curve generated by measuring the fractional volume of surface pores by the mercury intrusion method has no peak within the pore diameter range of 1×10 ˜1×10 Å.
