标题:一种n,N'-间苯撑双马来酰亚胺的制备方法
摘要:本发明公开了一种n,N'‑间苯撑双马来酰亚胺的制备方法,属于精细化工技术领域.将原料甲苯,马来酸酐和阻聚剂,加热到40~60oc进行溶解;将间苯二胺溶于强极性溶剂中后滴加入反应容器中,滴加完后保温,加入催化剂后加热升温至回流,直至不再有水被分出时停止反应;反应液冷却结晶后,经过过滤,用水洗涤,即得到浅黄色固体n,N'‑间苯撑双马来酰亚胺.本发明两步反应在同一反应容器中进行,不需要对中间产物进行分离纯化,其合成工艺操作简单,工作环境得到明显改善.目前市售产品液相色谱含量在75%~80%,用本发明制得的产品液相色谱含量可以达到90%以上,纯度高于目前市售产品.

摘要:Metal ligand-containing prepolymers, compositions containing metal ligand-containing prepolymers, methods of synthesizing metal ligand-containing prepolymers and the use of metal ligand-containing prepolymers in aerospace sealant applications are disclosed. The metal ligand-containing prepolymers have metal ligands incorporated into the backbone of the prepolymer. Cured sealant compositions comprising the metal ligand-containing prepolymers exhibit enhanced properties suitable for aerospace sealant applications.

摘要:Provided are new functionalized nitrile rubbers, which may optionally also be in partially or wholly hydrogenated form, and also a process for preparing them by metathesis of nitrile rubbers in the presence of a metathesis catalyst and at least one functionalized allyl compound. The new functionalized nitrile rubbers are suitable for producing vulcanizable mixtures and allow the production of vulcanizates having very stable networks. Also made possible, in particular, is the synthesis of block copolymers.

摘要:Bis(sulfonyl)alkanol-containing polythioethers, compositions containing bis(sulfonyl)alkanol-containing polythioethers, methods of synthesizing bis(sulfonyl)alkanol-containing polythioethers and the use of bis(sulfonyl)alkanol-containing polythioethers in aerospace sealant applications are disclosed. The bis(sulfonyl)alkanol-containing polythioethers have bis(sulfonyl)alkanol groups incorporated into the backbone of the polythioether. Cured sealant compositions comprising the bis(sulfonyl)alkanol-containing polythioethers exhibit enhanced properties suitable for aerospace sealant applications.
