| titleOfInvention | Monoamine bisphenol type asymmetry three-functionality-degree quinoxalinyl benzoxazine and preparation method thereof |
| abstract | The present invention relates to a kind of asymmetric three-functionality-degree quinoxalinyl benzoxazine and preparation method thereof.Using 4 dihydroxy benzils and 4 nitro-o-phenylenediamines as raw material, the quinoxaline intermediate containing a nitro and two phenolic hydroxyl groups is synthesized, mono amino bis-phenol base quinoxaline is obtained through being catalyzed reduction, again with bigcatkin willow aldehyde reaction, generate the phenolic compounds of quinoxaline three of the amine groups containing methylene, ring-closure reaction is carried out after sodium borohydride reduction, then with primary amine and paraformaldehyde, obtains a kind of monoamine bisphenol type asymmetry three-functionality-degree quinoxalinyl benzoxazine monomer.The present invention is by means of quinoxaline molecule possessed excellent heat resistance in itself, by introducing flexible alkyl chain and polymerizable groups, so that such monomer has relatively low fusing point and extra polymerization crosslinking position, so as to improve processing characteristics, plus the introducing of Geng Duo oxazine rings, its Polybenzoxazine resin shows excellent heat resistance and good mechanical property, available for manufacture high performance structures material etc.. |
