Stability of polydiorganosiloxane polymers

有机硅聚合物在全球范围内广泛应用，如密封剂、润滑剂、涂料等。然而，那些用于室外应用的有机硅受到许多恶劣环境因素的影响，如紫外线辐射、水分、盐和磨料。****特别感兴趣的是硅树脂聚合物随着时间的推移排斥水的能力。这一特性已被证明受到用于从反应容器中去除聚合物引发剂的中和剂的影响，并最终受到最终硅胶产品的影响。****因此，我们建议研究有机硅的长期稳定性，并比较不同中和化合物对CSL硅树脂公司生产的有机硅聚合物分解的影响。这项研究的一个关键组成部分将是了解分解过程，其速率，以及随着硅酮分解而形成的附属化合物

Silicone polymers are used in a number of applications globally, as sealants, lubricants, coatings, etc. However, those silicones that are used for applications outside are subjected to a number of harsh environmental factors such as UV radiation, moisture, salts, and abrasives. ****Of particular interest is the capacity of the silicone polymers to repel water over time. This property has been shown to be affected by the neutralizing agent used to remove the polymer initiator from the reaction vessel, and ultimately the final silicone product.****As a result we are proposing to study the long-term stability of silicones and comparing the affect(s) that different neutralizing compounds have on the decomposition of the silicone polymers being manufactured by CSL Silicones, Inc. A key component of this study will be understanding the decomposition process, its rate, and the affiliated compounds that form as the silicone breaks down.**
