    摘要: Plastic particles showing improved behavior upon extrusion, comprising coating the particles with a fused layer of certain waxes or polymeric materials; and a method of preparation, comprising heating the plastic particles to a temperature just below the softening or fusing temperature of the additive while blending the particle in a high intensity blender, introducing the additive and maintaining intense blending until the temperature is above the fusing temperature of the additive, and discharging the coated particles from the blender.
