    摘要: A process for preparing pellets of a hydrolyzed ethylene-vinyl acetate copolymer which comprises extruding a solution of a hydrolyzed ethylene-vinyl acetate copolymer in methanol or a mixture of water and methanol into a coagulating liquid in the form of a strand, and cutting the strand into pellets, the coagulating liquid consisting essentially of an organic solvent having a boiling point of not more than 100.degree. C., and being compatible with methanol but not being capable of dissolving the hydrolyzed ethylene-vinyl acetate copolymer. According to the present invention, the pellets from which impurities such as sodium acetate can be efficiently removed, and which have excellent thermal stability and moldability can be obtained in high productivity.
