摘要
简述通过改变聚合物多元醇结构 ,选择适当多异氰酸酯和扩链剂 ,在聚氨酯分子内引入杂环 ,用其他树脂进行改性 ,加入填料 。
The methods to improve the property of thermal-deformation resistance of polyurethane elastomers ,for example, to change the polymer polyol structure , to select the proper polyisocyanates and chain extender , to introduce the heterocycles into polyurethane molecules , to improve the property with other resins , to add fillers and to change the process conditions etc were briefly introduced.
