摘　　要：化学产品工程是化学工程学科的新拓展,其核心研究内容是化学品结构的精确定制.聚合物产品具有复杂的多层次结构,其中分子结构和分子的聚集态结构是决定聚合物性能的最主要结构层次.聚合过程可在很大程度上决定聚合物的分子结构和聚集态结构.近年来,本研究组在活性聚合机理和共聚动力学研究的基础上,针对各种链结构目标,建立了半连续聚合过程的模型化方法和操控聚合过程的计算机程序,实现了多种聚合产物分子结构的精确定制,制备了一些全新的高性能或特殊性能的聚合物.同时,通过反应器内合金化方法和活性界面细乳液聚合的方法尝试进行了聚合物原生聚集态结构的定制.本文综述了上述研究工作,并对未来研究的发展进行了展望.Chemical product engineering represents an emerging discipline rooted to chemical engineering. Its core content of research lies in precision production of chemical structures. Polymer products contain complex structures at multiple scales. Polymerization processes, to a large extent, determine polymer chain microstructures and morphologies. In the recent years, we developed various polymerization processes and produced polymers having precisely designed chain microstructures. These polymer products showed high performances and superior material properties in targeted applications. Our methodology employs kinetic modeling combined with reactor technologies, based on extensive mechanistic research on polymerization mechanisms. In controlled/living radical （co） polymerization, we developed a novel model-based computer-programed semi-batch copolymerization technology that allows unprecedented precise control over end-to-end copolymer composition of individual chains. In catalytic polymerization of olefins, we developed a reactor technology for in-situ production of polyolefin alloys. This paper provides a brief summary of the recent advances in the polymer product engineering researches.
