Embodiment 1
[0040]7.2g of 1-naphthol was dissolved in 300g of cyclohexanone, then at room temperature and under stirring, gradually added 17.4g of commercially purchased poly(maleic anhydride-co-methyl vinyl ether) powder (18459-4 , produced by Aldrich Co.). After adding, the reaction mixture was heated to 140° C., and after reacting at this temperature for 4 hours, the reaction solution was cooled to 100° C. or a lower temperature, and then 13.7 g of N-(2,4-dinitrobenzene was added base) phenylenediamine (disperse yellow 9), and the reaction mixture solution was heated to 140° C. for 4 hours. Then, the reaction solution was cooled to room temperature, and the reaction solution was precipitated with isopropanol. The precipitate was collected by filtration and dried under vacuum to obtain 31 g of polymer solid. The GPC analysis that adopts the dimethylformamide that adds lithium chloride as mobile phase and polyethylene oxide as standard substance shows that the weight-average molecular ...
Embodiment 2
[0041] Embodiment 2 (polymer synthesis 2)
[0042] Dissolve 9.7 g of 9-hydroxyanthracene in 320 g of cyclohexanone, then gradually add 17.4 g of commercially purchased poly(maleic anhydride-co-methyl vinyl ether) powder (18459-4 , produced by Aldrich Co.). After adding, the reaction mixture was heated to 140° C., and after reacting at this temperature for 4 hours, the reaction solution was cooled to 100° C. or a lower temperature, and then 13.7 g of N-(2,4-dinitrobenzene was added base) phenylenediamine (disperse yellow 9), and the reaction solution was heated to 140° C. for 4 hours. Then, the reaction solution was cooled to room temperature, and the reaction solution was precipitated with isopropanol in a conventional manner. The precipitate was dried under vacuum to obtain 33 g of polymer solid. The GPC analysis that adopts the dimethylformamide that adds lithium chloride as mobile phase and polyethylene oxide as standard substance shows that the weight-average molecular ...
Embodiment 3
[0043] Embodiment 3 (polymer synthesis 3)
[0044] The phenol of 4.7g is dissolved in the cyclohexanone of 280g, then under stirring at room temperature, add gradually the poly(maleic anhydride-co-methyl vinyl ether) powder (18459-4, by Aldrich Co. production). After adding, the reaction mixture was heated to 140° C., and after reacting at this temperature for 4 hours, the reaction solution was cooled to 100° C. or a lower temperature, and then 9.65 g of 1-aminoanthracene was added, and then the reaction solution was heated at 140° C. C for 4 hours. Thereafter, the reaction solution was cooled to room temperature, and the reaction solution was precipitated with isopropanol in a conventional manner. The obtained precipitate was dried in vacuo to obtain 25 g of polymer solid. The GPC analysis that adopts the dimethylformamide that adds lithium chloride as mobile phase and polyethylene oxide as standard substance shows that the weight-average molecular weight (Mw) of the polym...
