| 摘 要： | 以醇为酯化剂,对超支化苯乙烯-马来酸酐(BPSMA)进行酯化,考察了反应温度、时间、酯化剂结构及用量等对超支化苯乙烯-马来酸酐酯化物(BPSME)酯化度的影响,在优化实验的基础上制备了以甲醇为酯化剂的超支化苯乙烯-马来酸酐共聚物酯化物(M-BPSME),探讨了M-BPSME对颜料红122的分散性能。结果表明BPSMA与甲醇发生了酯化反应,且较佳的反应时间为6 h,酯化温度80℃。分散结果表明,相同条件下线型苯乙烯马来酸酐(LPSMA)、BPSMA、M-BPSME对颜料红122的分散效率为M-BPSMEBPSMALPSMA,且MBPSME作分散剂的颜料分散体系的离心稳定性和冻融稳定均在97%以上。 |

| Abstract: | The hyperbranched styrene-maleic anhydride polymers were modified with alcohol, and a series of modification conditions, such as reaction temperature, time, types and dosages of alcohol, were investigated in detail. Aimed at the dispersity for red P.R122, Esters of hyperbranched styrene-maleic anhydride copolymer M-BPSME were preparated on the basis of optimizing conditions. M-BPSME has been characterized by FTIR spectra, and has higher esterification degree when reactive time is 6h and temperature 80oC. Besides, the dispersing ability of LPSMA, BPSMA and M-BPSME to red P.R122 was as follows: M-BPSME > BPSMA > LPSMA. Interesting, BPSME showed high dispersity to red P.R122, that centrifugal and heat stabilities were over 97%. |
