Transparent thermoplastic resin pellet manufacturing method

Abstract

A method for producing a transparent thermoplastic resin pellet comprising a step of kneading a transparent thermoplastic resin with a kneader under a condition under which a damage history calculated according to the following formula is 500 to 2,500: Damage history={Residence time (tr)}×{Shear rate (γ)} Residence time (tr)=(W×H×L)/Q Shear rate (γ)=(π×D×N)/H in the formulae, W represents a screw groove width (pitch) [cm]; H represents a screw groove depth [cm]; L represents a screw length [cm]; Q represents a resin supply amount [g/s]; D represents a screw diameter [cm]; and N represents a screw rotation number [rps].
