TRANSPARENT THERMOPLASTIC RESIN PELLET MANUFACTURING METHOD

摘要

A transparent thermoplastic resin pellet manufacturing method comprising a process of kneading a transparent thermoplastic resin using a kneader under conditions such that the damage history calculated using the following formulas is 500 - 2500. Damage history = retention time (tr) × shear rate (gamma) Retention time (tr) = (W×H×L)/Q Shear rate (gamma) = (pi×D×N)/H [In the formulas, W represents the screw channel width (pitch) [cm], H the screw channel depth [cm], L the screw length [cm], Q the resin supply rate [g/s], D the screw diameter [cm], and N the screw rotation speed [rps].]
