聚合物是在建筑，工程和无数商业产品中使用的无处不在的材料。这些应用可能与医疗设备，药品，食品和饮料包装以及个人护理化妆品中使用的聚合物材料一样多。它们是由通常是有机的键合分子的链条制成的，但在某些情况下甚至可能是无机的。
Natural rubber is a polymer consisting of the simple hydrocarbon isoprene, while polyethylene (PE) is a synthetic plastic manufactured from ethylene monomers. A typical polyethylene may consist of up to 200,000 monomers, the composition, and concentration of which can have a significant impact on the qualities of the end-product.
Polymer Analysis and Polymerization
Polymerization is the process that causes small molecule monomers to covalently bind with one another and form tough interlinking polymer chains. The polymer chain can be formed using a range of chemical species by heating or pressurizing samples in the presence of catalyzing agents. An assortment of engineering techniques is used to manufacture polymers with varying molecular weights and chemical-mechanical properties. For example, some epoxy resins are made through copolymerization with an amine, a process in which the polymer reacts with a hardener to form the final product.
从根本上讲，给定聚合物产物的物理特性和适用性取决于聚合过程中使用的单体，添加剂和共聚物的组成和稳定性。原材料的分析通常先于聚合以进行质量控制程序。继续以共聚的示例，聚合物分析可能会揭示材料的变形特性，然后可以通过制造过程中的其他固化或硬化阶段来修改。
Polymer Analysis and Deformulation
Polymer analysis is also a routine part of product deformulation and failure analysis. Mass spectrometry and gel permeation chromatography are widely used methods for assessing the composition, and both the primary and residual concentration of monomers in an end-product. These methods can also be used to measure the molecular weights of polymers of up to millions of molecular weight.
The importance of polymer analysis cannot be understated. It is used for both research and development, quality control, and failure analysis in an enormous range of industrial and commercial applications. Products from biodegradable plastic bags to carbon-reinforced-polymer car parts depend on polymer analysis to ensure that the material can withstand application-specific strains and conditions.
