However, the pure PET polyester sheet is brittle and has insufficient impact resistance, which limits the wider application. Based on the above, the conventional method improves the impact resistance of PET by toughening and modifying the PET, but the toughening and modifying almost all affect the transparency of the PET polyester sheet, and the toughness of the PET polyester sheet is improved, but the optical performance of the PET polyester sheet is reduced, so that the PET polyester sheet is limited in application in the optical field. Therefore, there is a need to develop a masterbatch with both high transparency and high toughness, which can be added to PET polyester sheets to meet the market demand for PET polyester sheets with high transparency and high toughness.
