摘要： A method of refining a polymer resin material is provided. The method comprises melting and subjecting the resin material to shear stresses in a range of 250 kPa to 400 kPa to form a refined resin material. The refined resin material may be extruded, solidified and cut into reduced microgel resin pellets, which may be subsequently melted and extruded to form a reduced microgel film.
