ABSTRACT:
A process for preparing a shaped article made of hydrolyzed ethylene-vinyl acetate copolymer having an improved impact resistance by conditioning the shaped article to contain water within the range of 0.2 to 3.0 % by weight to the article. The impact resistance of the shaped article can be improved without losing the advantageous characteristics of the copolymer and the improved article can be suitably employed as engineering plastics.
