Abstract
The invention relates to a synthesis method of a biaxially orientated polyester film. The synthesis method comprises the following steps: carrying out reduced pressure distillation on methyl methacrylate, ethyl acrylate, ethanol and benzoyl peroxide for refining, wherein the benzoyl peroxide is dissolved in chloroform, filtered, recrystallized in methanol and repeatedly processed for standby application; sequentially adding reaction monomers including methyl methacrylate, the ethyl acrylate and an initiator to a four-mouth flask equippted with a stirrer, a temperature gauge, a condenser pipe and an N2 ingress pipe; dropwise adding mixed liquid of the ethyl acrylate and the ethanol to the reaction flask by a dropping funnel, replenishing the initiator, and carrying out reaction at constant temperature; dropwise adding ammonium hydroxide under fiercely stirring to neutralize reaction liquid and adding an appropriate amount of water for dilution to obtain semitransparent blue-suffused hydrosol; and taking out a part of the hydrosol and drying for later use and adding water to a part of the hydrosol to dilute film to obtain the biaxially orientated polyester film. The synthesis method is simple and is low in cost. The synthesized biaxially orientated polyester film is strong in designability, good in stability, high in transparency and good in rheological property.
