新型聚合物紫外线吸收剂的合成研究

COMPOSITION RESEARCH OF A NEW KIND OF ULTRAVIOLET ABSORBER

异氰脲酸三环氧丙酯（Ⅰ）与高级脂肪酸（Ⅱ）及２，４－二羟基二苯甲酮（Ⅲ）在催化剂作用下，分两步反应合成了两种高分子量的紫外线吸收剂ＵＶ－９８１和ＵＶ－１００９，并对其合成工艺条件进行了探讨。适宜工艺条件为：原料比：Ⅰ∶Ⅱ∶Ⅲ＝１∶１∶２，反应温度：８０～１１０℃，反应时间：ｔ－１＝３～５ｈ，ｔ＿２＝５～８ｈ。

Abstract This paper is devoted to the preparationmethod of two new high relative molecularmass ultraviolet absorbers UV-981, UV-1009. In this method,triglycidyl isocyanurea(Ⅰ)reacts with fatty acid(Ⅱ)and 2,4-dihy-droxybenzophenone(Ⅲ).The best synthesisconditions are as follows Ⅰ∶Ⅱ∶Ⅲ=1∶1∶2(mol),reaction time t_1=3～5h,t_2=5～8h,reaction temperature80～110℃.
