摘　　要：介绍了不饱和聚酯树脂稳定化方面的新近研究进展,包括不饱和聚酯制品如玻璃钢表面新型涂层及新型稳定剂(紫外线吸收剂、受阻胺光稳定剂和抗氧剂)等。研究表明,只使用单一的稳定剂效果不佳,必须将主抗氧剂、副抗氧剂和其他添加剂(例如某些环氧化合物)并用,才能取得较好的稳定效果。Recent advances in stabilization of unsaturated polyester resin were reviewed in this paper, including novel coatings of unsaturated polyester procucts （e. g. glass fiber reinforced plastics ） and various stabilizers, such as ultraviolet absorbent, hindered amine light stabilizers（HALS） and antioxidant. The results showed the effect was not good using single stabilizer. The combined use of main and side antioxidant and other additives （e. g. some epoxy compounds） had the best effect on maintaining light oxidative stabilization of UP.
