本文介绍了4,4＇-双（对叔丁基苯并噁唑-2-基）二苯乙烯的合成方法。以对氰基氯苄和对叔丁基邻氨基苯酚为原料分两步合成而制得。将制得的荧光增白剂用于PE（聚乙烯）、PP（聚丙烯）、PVC（聚氯乙烯）、PET（聚对苯二甲酸乙二醇酯）,均有较好的增白效果。通过实验得到在PE上的合适添加量为0.005%～0.02%。与目前市场上常用的其他双苯并噁唑二苯乙烯类荧光增白剂如荧光增白剂OB-1、OB-2相比,在PP上的增白效果更优异。

A new kind of fluorescent brightener,4,4′-bis（5-tert-butyl-benzoxazol-2-yl）stilbene,has been synthesized from 4-cyanobenzyl chloride and 4-butyl-2-aminophenol by two steps.It was found that the whitening effects of the product on PE（polyethylene）,PP（polypropylene）,PVC（polyvinylchlorid） and PET（polyethylene terephthalate） were good.The proper concentration for PE was 0.005% to 0.02% by weight.Comparing with other bisbenzoxazole stilbene fluorescent brightener such as OB-1 and OB-2,it presented better whitening effect when whitening PP.
