摘　　要：通过正交实验对4,4'-二氯甲基联苯(BCMBP)自聚合反应的工艺条件进行优化,对4种影响因素进行考察,得到影响产品比表面积大小因素的顺序为:预聚合时间、预聚合温度、单体浓度和催化剂用量.在优化条件下所得树脂的比表面积为1 512.66 m2/g,树脂具有丰富的微孔和较高的聚合度.通过氮气吸附-脱附、SEM和热失重实验对树脂的孔径分布、微观形貌和热稳定性进行了研究.Orthogonal experiments were designed to explore the influences of some factors on the synthesis of 4,4＇-bis （chloromethyl）-1,1 ＇-biphenyl （BCMBP） self-polymerization resin based on the products＇specific surface area.The results showed that the order of factors influencing on resin＇s BET surfaces was as follows：prepolymerization time,prepolymerization temperature,concentration of BCMBP and catalyst.Under the optimized conditions,the BET surface of resin was as large as 1 512.66 m^2/g.The resin possessed rich microporous and high degree of polymerization.The pore structme,pore morphology and thermal behaviors were studied by nitrogen adsorption-desorption,SEM and TG-DTA.
