摘　　要：通过对共混体系玻璃化转变温度(T_g)的分析,研究了羰基化间戊二烯石油树脂与SBS的相容性。结果表明,间戊二烯石油树脂与SBS中的硬段PS不相容,经过羰基化处理后的树脂极性提高,相容性得到改善。羰基化处理时间为90min左右,羰基化石油树脂在共混体系中质量分数为20%以上,共混体系形成了均匀的连续相,2者完全相容。The compatibility ot-carbonylated plperylene petroleum resin and SBS was investigated by analysis of glass-transitiontemperature of blend systems.The results showed that piperylene petroleum resin and hard block PS phase of SBS are incompatible,butthe polarity of resin was improved after carbonylation,and the compatibility of resin and hard block PS phase was improved as well.The carbonylation time of resin is about 9{） min,and the content of carbonylated resin in petroleum resin/SBS blends is more than 20%.The blends formed a homogeneous continuous phase,and they are completely compatible.
