摘要
通过动态力学分析研究了苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)与加氢C5石油树脂(HC5R)共混体系的相容性,并考察了臭氧处理对共混体系的影响。结果表明,当HC5R用量为50份时,其与SBS中软段聚丁二烯相的相容性较好,只有1个玻璃化转变温度;随着臭氧处理时间的延长,HCR的极性增大;HCR与SBS分别经过臭氧处理120min和60min后,两者的相容性得到改善。
The compatibility of styrene-butadiene-styrene block copolymer(SBS)with hydrogenated C5 petroleum resin(HC5R)was studied by dynamic mechanical analysis.The effects of ozone treatment on properties of the blends were investigated.The results showed that the compatibility between HC5R and polybutadiene phase in SBS was good with increasing amount of HC5R to 50 phr,and the blends had one glass-transition temperature.With increasing ozone treating time,the polarity of HC5R increased.When HC5R and SBS were treat...
