Due to the ability of the bivalent magnesium cation to form stable chelate complexes with carbonyl compounds,magnesium methylate for example is used as a selective carbonyl condensing agent.Three synthesis routes was proposed based on literatures and comprehensive comparison with other ways.First,Magnesium methylate is prepared by reacting magnesium metal with dry methanol.The magnesium salts of higherprimary alcohols,i.e.alcohols with ≥ 2 carbon atoms,do not react directly with pure alcohols under normal conditions.In fact catalysts are required to set the reaction in motion and the preparation is performed under pressure at the higher temperatures.

一、直接合成法：本文将镁与无水甲醇直接反应制得甲醇镁；"更高级"的醇(比如C≥2的醇)在无催化剂的条件下无法直接和镁进行反应，本文以CCl_4为催化剂将无水乙醇与镁直接反应制得乙醇镁，但是以原甲酸三乙酯为催化剂无水乙醇与镁无法反应；不论是以CCl_4为催化剂还是以原甲酸三乙酯为催化剂，丙醇均无法与镁直接反应。

The effects of NaAA content on the mechanical properties and water-swellable properties were studied. The experimental results show that NaAA has good reinforcement for the EVM vulcanizate. EVM vulcanziate reinforced by NaAA has higher water absorbing rate and equilibrium water absorbing ratio. When the NaAA content is 50 phr, the maximum water-absorbing ratio of EVM vulcanziate is 278.3%. With the incorporation of ion into immersing media, the water-absorption ratio of EVM vulcanizates decreases. FT-IR analysis confirms that NaAA formed in the process of compounding and underwent polymerization during vulcanization.

结果表明，NaAA对EVM硫化胶具有明显的增强效果；NaAA原位改性的EVM硫化胶具有较好的吸水膨胀性能，NaAA用量为50phr时，最高吸水率为278.3%；浸泡介质中离子的引入使EVM硫化胶的吸水率下降；FT-IR分析表明，在混炼过程中生成了NaAA，在硫化过程中NaAA发生聚合反应。

The CPE/LiAA and CPE/NaAA compounds have good curing properties. The tensile strength is about 30MPa when the in situ formed LiAA or NaAA content is 30phr.

其混炼胶的硫化速度快、硫化程度高；当其含量为30份时，硫化胶拉伸强度可达30MPa左右；硫化胶吸水膨胀速度快，浸水24小时后原位合成LiAA和NaAA改性CPE硫化胶的吸水膨胀率分别可超过120％和85％。
