| titleOfInvention | Novel bismaleimide and production thereof |
| abstract | NEW MATERIAL:3,4-Bismaleimide diphenyl ether of the formula. n USE: A starting substance for bismaleimide resins. n PREPARATION: 3,4'-Diaminodiphenyl ether is mixed with 2 equivalent amount of maleic anhydride in an inert solvent such as diethyl ether to form amide- carboxylic acid, then the product is dehydrative cyclization to give the compound of the formula. The dehydrative cyclization is carried out by heating the amide-carboxylic acid 80W200°C or by using a condensation agent such as acetic acid at 10W80°C for 20minW8hr. When a condensation agent is used, a catalyst such as sodium acetate may be added, when needed. n COPYRIGHT: (C)1989,JPO&Japio |
