聚氨酯胶粘剂的合成控制和产品表征

The Synthetic Control and Product Characterigation of the Polyurethane Adhesive

本文研究聚酯型聚氨酯胶粘剂的合成工艺；考查了软段聚酯的组成，溶剂类型，投料方式，反应温度与时间，封端剂等因素对此类胶粘剂合成反应的影响并导出合理的控制反应条件；

In the article, the synthetic process of the polyuresterurethane Adhesive is studied,The influential fators such as the composition of the soft-segment, the type, the model of adding meteriels ,the temperature and the time of the reaction and the Chain end-stopper etc,are investigatad,And the conditions for controlling the synthetic reaction are providid Also the means of Characterigation and determinati on of the qualitg of the Adhesive and the middle product are decided.
