研究了两种硅烷偶联剂——乙烯基三乙氧基硅烷(A-151)和乙烯基三特丁基过氧硅烷对高硬度硅橡胶性能的影响，比较发现A-151不但可以显著改善高硬度硅橡胶的回弹性，而且使用方便、成本较低。

By contrasted with silica gel, the corn hull desiccants by hydrolyzation method and heat treatment method have advantages as stabilization on moisture adsorption, less water of reversible adsorption and high moisture adsorption ratio in high humidity. These desiccants have disadvantages as lower moisture ratio than silica gel in low humidity and slower moisture adsorption speed than silica gel. The corn hull desiccant by derivation method has advantages as high moisture adsorption ratio, high moisture adsorption speed, stabilization on moisture adsorption and hardly any water of reversible adsorption.

通过与变色硅胶干燥剂的对比，通过水解法和热处理法得到的玉米渣皮干燥剂的优点是吸水稳定，可逆吸附水少，在高湿度下吸水率高，不足是在较低的湿度下，吸水率比变色硅胶干燥剂略低，吸水速度比硅胶慢；通过衍生方法得到的玉米渣皮干燥剂的优点是吸水率高，吸水速度快，吸湿稳定持久，几乎不含可逆吸附水，不足是再生后产品容易结块。
