摘　　要：研究抽出物对氯丁橡胶(CR)及其并用胶玻璃化转变温度(T_(g))的影响。结果表明:抽出物对不同种类橡胶T_(g)的影响趋势不同,对于CR/顺丁橡胶(BR)并用胶(硫化胶),抽出物使BR的T_(g)升高,使CR的T_(g)降低,而对于CR/BR/天然橡胶(NR)并用胶,抽出物对NR的T_(g)降低作用小于对CR的T_(g)降低作用;对于不同的橡胶材料,抽出物对其T_(g)的影响程度不一样,抽出物对CR生胶的T_(g)影响不大。The effect of the extractables on the glass transition temperatures(T_(g))of chloroprene rubber(CR)and its blends was studied.The results showed that the influence trend of the extractables on the T_(g) of different types of rubber was different.For CR/butadiene rubber(BR)/NR blends(vulcanizate),the T_(g) of BR increased,and the T_(g) of CR decreased due to the presence of the extractables.In the case of CR/BR/natural rubber(NR)blends(vulcanizate),the reduction in T_(g) caused by the extractables was more significant for CR than for NR.For different rubber materials,the impact of the extractables on their T_(g) varied,and the extractables had little effect on the T_(g) of CR raw rubber.
