Beschreibung
Zusammenfassung:	The invention relates to a method for preparing polycarbonate by using electrophilic aromatic substitution. The method comprises the step of reacting diaryl carbonate with a structure as shown in a formula (I) with dichloromethyl benzene with a structure as shown in a formula (II). 本发明涉及一种利用亲电芳族取代制备聚碳酸酯的方法，包括具有式(I)结构的碳酸二芳酯与具有式(II)结构的二氯甲基苯的反应。
