In this project, we have prepared conveniently Si-Mg 1,1-difunctional group reagents-α-silylvinyl Grignard reagents by hydromagnesiation of alkynylsilanes; Se-Br 1,1-difunctional group reagents-α-bromovinylselenides by hydrobromination of alkynylselenides; Sn-Br and Sn-I 1,1-difunctional group reagents by hydrozirconation of alkynylstannanes followed by halogenating reaction.

Between 4-9L exposures, C2H4 has a desorption channel at 155-180K. C2H4 desorption at 130K maybe results from BrCH2CH2Br absorbs in Br atom toward surfaces, after C-Br bond scission, because C2H4 has no opportunity to touch surfaces so it desorbs at low temperature. C2H4 desorption at 210K is likely to be desorption limited that, BrCH2CH2Br docomposes to C2H4, only to desorb at higher temperature. This C2H4 desorption channel maybe comes from defect site desorption.

曝露量在4-9L之间，C2H4在155至180K的范围内也有脱附的管道。130K的C2H4脱附可能是因为BrCH2CH2Br分子以Br原子朝向表面的方式吸附，在断了C-Br键后，C2H4分子没有机会接触到表面在低温就脱附了。210K的C2H4可能是脱附所决定的，亦即BrCH2CH2Br分解后在表面形成C2H4，随后温度升高至较高温才从表面脱附，此C2H4管道也许是来自缺陷位置上的脱附。

The results showed that both LIR and LIR/aromatic oil could improve the processibility of NR/BR blend,and the plasticizing effect of the latter was more significant than that of LIR or aromatic oil alone resulting in lower compound viscosity,energy consumption and processing cost;and the NR/BR vulcanizate with LIR/aromatic oil possessed good physical properties and better dispersion of carbon black.

结果表明，LIR和LIR/芳烃油并用体系均能有效改善NR/BR混炼胶的加工性能，且后者的增塑效果较LIR或芳烃油单用时更为显著，其对应的混炼胶粘度较小，工艺能耗和成本较低；LIR/芳烃油并用体系对应的NR/BR硫化胶性能良好，炭黑在其中的分散性也较好。
