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/或用现有设备生产新的聚合物材料的需要，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因素。替代工艺包括使用生物可再生单体，以及在水相中聚合以产生纳米结构颗粒。聚合反应在较高的温度下进行，以便以可控的粘度和较低的溶剂含量生产聚合物。可控自由基技术也成为控制聚合物微观结构和性能的一种新手段。
