ABSTRACT:
Disclosed is a process for the formation of olefin-vinyl alcohol copolymer pellets which comprises mixing particles of the copolymer with water to obtain a wet cake containing about 20-70% solids by weight to thereby obtain a plasticized mass of the copolymer, thereafter extruding the copolymer at a temperature of about 5.degree.-7.degree. C. below the melting point of the mass through a nozzle to form a rod, and dividing the rod into individual pellets.
