NEW MATERIAL:An aromatic allylamine compound expressed by formula I (R 1 to R 4 are H, 1-4C alkyl or halogen). n USE: A raw material for thermosetting type polyimide resins excellent in processability, heat resistance and mechanical properties. n PREPARATION: For example, 4,4'-diaminodiphenylmethane is reacted with allyl chloride in the presence of NaOH in dimethyl sulfoxide solvent to provide a compound having average 3 allyl groups. The resultant compound is further reacted with the allyl chloride in the presence of triethylamine in methylene chloride to afford the objective compound expressed by the formula (all the R 1 to R 4 are H). n COPYRIGHT: (C)1992,JPO&Japio |
