Through changing various conditions, the conversion of polymerization was determined gravimetrically by sampling with an injector at different time in the course of polymerization system and it was found that conversion was increased linearly firstly and non-linearly finally along with reaction time.

通过改变单一聚合条件，在不同反应时间，利用注射器进行取样，称重法测定聚合物转化率，考察聚合条件的影响，说明此合成体系受单体/引发剂、催化体系、聚合温度、反应时间等因素的影响(如聚合温度90℃，反应时间12h时，产率可达90%以上)。

The setting of parameters is as follows; sample weight of 0.15g, the maximum work current of 350mA, the flow capacity of carrying gas of 3L/min, the purity of oxygen of 99.99%, the precleaning time of l0s, the predelay time of 10s, the analytical period of 60s, the comparison level of 1.0%. The blank of ceramic crucibles could be reduced to minimum by burning them for 2h at 1100℃.

Every group rats were divided into two parts with the same rats. At last the rats were redivided ,then them were killed and their brains were excluded after one hour.4 hours or one week.Results PO2 and cerebral blood flow of E-selectin 2mg/kg group were higher than that of saline and lower than that of l0mg/kggroup(p.01).The volume of cerebral infarct and blood speed of E-selectin 2mg/kg group was smaller than that of saline and larger than that of l0mg/kg group(p.01).At the same time PCh.speeds.flows and the volume of infarct were related with the time (p.01).Conclusion E-selectin can effectively increase PC2 and rCBF after ischemia and reperfusion .reducing infarct volumes and speeds of blood at the same time . Artificial synthetic E-selectin can effectively reduce the reperfusion injury following cerebral ischemia.
