摘　　要：聚合物光纤(POF)具有制造简单、价格便宜、接续快捷、抗冲击强度高、抗辐射等优点,是短距通信网的理想选择。以甲基丙烯酸甲酯(MMA)为基质,采用界面凝胶聚合制备了梯度型聚合物光纤预制棒,利用拉丝机将预制棒熔融拉丝,获得性能良好的聚合物光纤。试验中,利用离心旋转和逐级升温等措施避免了气泡的产生,初步比较了不同保温时间对预制棒折射率分布的影响,对预制棒的制备有一定的参考意义。Possessing the advantages of easy to make,low cost,fast to connect,high impact strength and radiation resistance,the polymer optical fiber（POF） is the ideal choice for short distance communication networks.By adopting interfacial-gel polymerization with MMA as the base material,the prefabricated rod of the polymer optical fiber featuring gradient index of refraction is prepared,then the prefabricated rod is melted and drew by the drawing bench,and finally the polymer optical fiber with high performance is acquired.During the experiment,the bubble is avoided by centrifugal rotation and gradual temperature increasing,the impact on the distribution of index of refraction to the prefabricated rod with different temperature holding time is compared preliminarily,which posses certain reference value for making the prefabricated rod.
