The invention relates to the technical field of poly (p-chloroalkylphenol) glycidyl ether, in particular to hyperbranched poly (p-chloroalkylphenol) glycidyl ether, a preparation method of the hyperbranched poly (p-chloroalkylphenol) glycidyl ether and a preparation method of bisphenol A epoxy resin modified by the hyperbranched poly (p-chloroalkylphenol) glycidyl ether. According to the invention, one or two of 4-chloromethylphenol and 4-(2-chloroethyl) phenol are selected to prepare hyperbranched poly (p-chloroalkylphenol), and then the hyperbranched poly (p-chloroalkylphenol) glycidyl ether is prepared from the hyperbranched poly (p-chloroalkylphenol). The hyperbranched poly (p-chloroalkylphenol) glycidyl ether is used as a toughening agent to modify the bisphenol A epoxy resin, and the impact strength and tensile strength of the modified bisphenol A epoxy resin Tg are improved. 本发明涉及聚对氯烷基酚型缩水甘油醚技术领域，具体涉及超支化聚对氯烷基酚型缩水甘油醚及其制备方法、采用其改性的双酚A型环氧树脂的制法。本发明选用4-氯甲基苯酚、4-(2-氯乙基)苯酚中的一种或两种制得超支化聚对氯烷基苯酚，再通过超支化聚对氯烷基苯酚制得超支化聚
