Title:
METHOD FOR PRODUCING CRYSTALLINE RESIN SHEET
Document Type and Number:
WIPO Patent Application WO/2023/243668
Kind Code:
A1
Abstract:
This method for producing a crystalline resin sheet comprises rolling a molten state sheet-shaped crystalline resin composition between a pair of sandwiching rollers. The crystalline resin composition includes a crystalline resin and a molten state nucleating agent. When the radius of the pair of sandwiching rollers is noted as R, the average thickness of the sheet after rolling is noted as L, and the sheet withdrawal speed in the pair of sandwiching rollers is noted as V, an adjustment is performed such that the average elongation strain rate ε (R, L, V) in the sheet elongation direction represented by a specific formula is more than 30 s-1 but no more than 80 s-1.
