丙烯酸松香蔗糖聚氨酯/聚丙烯酸酯IPN的合成与性能

Synthesis of Rosin Acrylate Sucros-ester Polyurethane/polycrylate IPN

以蔗糖、松香、丙烯酸、甲苯二异氰酸酯等合成新型丙烯酸酯松香蔗糖聚氨酯 ( PU ) ,以PU和聚丙烯酸 ( PA)共混制得 PU / PA IPN。应用 FTIR、TGA、DSC等手段对产品的结构及性能测试。讨论了三异氰酸苯酯 -三羟甲基丙烷及 PA的添加量对产品性能影响。

A new type of butylacrylate-rosins-sucrose ester polyurethane was synthesized and a IPN material was prepared by blending it with polyacrylate(PA). The structure and property of the product were examined by FTIR, TGA and DSC. The effects of TDI-TMP and PA on the product were investigated.
