The need to increase production rates and/or produce new polymeric materials with existing equipment as well as the ability to replace processes with cost-effective and environmentally-friendly versions are key drivers in the polymers industry. Alternative processes include the use of biorenewable monomers, and polymerization in water-phase to produce nanostructured particles. Polymerizations are conducted at higher temperatures in order to produce polymer at manageable viscosities with reduced solvent content. Controlled-radical techniques have also emerged as a new means to control polymer microstructure and thus properties.

提高生产率和/或利用现有设备生产新的聚合物材料的需求，以及用具有成本效益和环境友好的版本取代工艺的能力，是聚合物行业的关键驱动力。替代方法包括使用生物可再生单体和在水相中聚合以产生纳米结构颗粒。聚合在较高温度下进行，以生产具有可管理粘度和降低溶剂含量的聚合物。可控自由基技术也作为一种新的手段来控制聚合物的微观结构和性能。
