Smoke Suppression of Vinyl Polymers by Reductive Crosslinking Agents

该项目涉及一种新的PVC抑烟和阻燃方法，该方法涉及通过聚合物基质中金属化合物形成的零价或低价金属还原偶联聚合物链。 拟议的研究的具体目标包括进一步的机制的理解还原偶联化学，因为它适用于氯化聚合物。 此外，还将进行潜在抑烟剂的合成和添加剂的筛选。 最终，将在此开发的技术扩展到其他商业聚合物将被追求。有了这个奖项，有机和高分子化学计划支持教授威廉H。小斯塔恩斯和罗伯特·D。威廉和玛丽学院的派克。 Starnes教授和Pike教授将运用他们各自的聚合物和有机金属化学知识来解决PVC塑料中的烟雾和阻燃问题。 这是通过使用金属催化剂进行的，金属催化剂将在燃烧过程中遇到的条件下使小的挥发性分子聚结成更大的非挥发性颗粒。

This project deals with a new method of PVC smoke suppression and fire retardance, which involves the reductive coupling of the polymer chains by zero- or low-valent metals that are formed from metal compounds within the polymer matrix. Specific objectives of the proposed research include a furtherance of the mechanistic understanding of reductive coupling chemistry as it applies to chlorinated polymers. In addition, the synthesis of potential smoke suppressants will be undertaken and additives screened. Ultimately, extension of the technologies developed herein to other commercial polymers will be pursued.With this Award, the Organic and Macromolecular Chemistry Program supports the research of Professors William H. Starnes, Jr. and Robert D. Pike of the College of William and Mary. Professor Starnes and Pike will apply their respective knowledge of polymer and organometallic chemistry to the problem of smoke and fire retardance in PVC plastics. This is undertaken through the use of metal catalysts that will cause the coalescence of small, volatile molecules into larger, sooty particles under the conditions encountered during combustion.
