A steel bar is washed and dried, and then put into a glass pipe which is sealed to obtain stirring magneton; a mixed solvent of Gamma-methacrylate oxide propyl trimethoxy silane and methanol is prepared and added with an organic base to obtain a pre-bonding solvent; the stirring magneton is immerged into the pre-bounding solvent, and the outer surface of the glass pipe of the stirring magneton is bonded with a layer of silane substance with alkenyl; a reactive monomer mixture and a pore-forming agent mixed solvent are evenly mixed and then added into a container, the stirring magneton after the pre-bounding is put into the container which is sealed and then put into a water bath; after reaction, the container is removed, the stirring magneton coated with a polymer is taken out and put into a extractor and extracted by using a solvent; or the stir bar is immersed into the solvent till no impurity can be checked in the solvent, thereby obtaining the product.

将铁条清洗干燥，放入玻璃管内，密封得搅拌磁子；配制γ-甲基丙烯酸氧丙基三甲氧基硅烷与甲醇的混合溶液，加入有机碱得预键合溶液，将搅拌磁子浸入预键合溶液，在搅拌磁子的玻璃管外壁键合一层带烯基的硅烷化物质；将反应单体混合剂和致孔剂混合溶液混匀后倒入容器中，将预键合后的搅拌磁子放入容器，密封后置于水浴中，反应后除去容器，取出涂有聚合物的搅拌磁子，置于提取器中，以溶剂提取，或将搅拌棒置于溶剂中浸泡至溶剂中无杂质检出，得产物。

Methanol molecule participates in the proton transfer process, which takes place by a intermolecular six-membered proton-transfer transition state structure instead of the intramolecular four- membered. Consequently, the activation energy of the proton-transfer process is reduced greatly,resulting in the carbon-carbon bond formation process become the rate-determining step. The results are consistent with Aggarwal's the latest dynamics experiments.

CH3OH分子参与质子转移过程，使得原本通过四元环结构过渡态的质子转移过程通过六元环结构过渡态实现，从而极大地降低了质子转移过程的活化能，碳-碳键形成过程进而成为反应的速度控制步骤，研究结果与Aggarwal等的最新动力学研究成果相吻合。
