摘　　要：以聚异丁烯(PIB,Mn=2300,PDI=2.3)、马来酸酐和α-烯为原料,通过自由基引发合成三元共聚物聚异丁烯丁二酸酐(PIBSA),再与四乙烯五胺发生胺化反应生成聚异丁烯丁二酰亚胺(PIBSI)无灰分散剂。用1H-NMR、IR和GPC对PIBSA和PIBSI的结构和分子量进行表征,用热失重法(TG)和油泥斑点法分别测试PIBSI的热稳定性和低温分散性。结果表明:当加入8 wt.%的PIBSI时,低温油泥分散性提高了2.07倍。Terpolymer polyisobutylene succinic anhydride （PIBSA） was prepared by the free radical terpolymer reaction of polyisobutylene （Mn=2300, PDI=2.3）, alpha olefin and maleic. Po（yisobutylene succinic imide （PIBSI） ashless dispersant was obtained after the reaction of P1BSA with tetraethylenepentamme. PIBSA and PIBSI were characterized by ^1H-NMR, GPC and FTIR. The thermal stability and low temperature dispersion performance of PIBSI was evaluated by TG and blotter spot test. The results showed that low-temperature sludge dispersibility increased 2.07 times when adding 8 wt. % PIBSI.
