摘要：
A method and apparatus are provided for continuously producing a polymer pellet efficiently in which, in storing, transporting or feeding to a processing apparatus, the obtained pellets containing the adhesive polymer do not easily mutually adhere, and handling thereof is excellent. The method comprises a step of deforming at temperatures of about 30 to 150° C. under pressure an adhesive polymer coated with a thermoplastic polymer, and a step of cutting the deformed portion of the coated polymer.
