Polymers with low average molecular weight and a low polydispersity index have many applications in the paint and coating industry. Production of such polymers requires tight control of the molecular-weight distribution of the polymers. Control is achieved by adjusting the temperature, diluting the reaction mixture, and adding chain transfer agents, mercaptans, and cobalt glyxins. Liquid-phase, high-temperature, free-radical polymerization is used to produce low average-molecular-weight polymers. Preliminary results also show that high-temperature, free-radical polymerization of butyl acrylate (BA) can lead to the production of low poly-dispersity index, BA polymers. Thus, high-temperature polymerization offers better controllability to produce the desired polymer product.This NSF GOALI project is a joint effort between Drexel University and DuPont aimed at improving the quality of acrylate and styrenic, homo-polymers and copolymers produced via high-temperature, solution polymerization. This Faculty-in-Industry project is motivated by the need to take a fundamental approach to improve the product quality. The PI Soroush will spend one year in DuPont's Marshall Laboratory to pursue the following research and education activities: *Study the kinetics of liquid-phase, high-temperature (140-200oC), free-radical, BA and butyl methacrylate (BMA), homopolymerization reactions to develop mathematical models for high-temperature, BA and BMA, semi-batch, polymerization reactors. *Calculation of optimal temperature and feed flow-rate profiles as well as loading conditions for high-temperature, semi-batch, BA and BMA, polymerization reactors. *Formulation of a set of industrial, process modeling, open-ended problems to be assigned as projects to undergraduate students taking the process modeling courses at Drexel University.

平均分子量低和低分散指数的聚合物在油漆和涂料行业中具有许多应用。 这种聚合物的产生需要严格控制聚合物的分子量分布。 通过调节温度，稀释反应混合物，添加链传递剂，近豆茶和钴甘霉素来实现控制。 液相，高温，自由基聚合用于产生低平均分子量的聚合物。 初步结果还表明，丁基酯（BA）的高温，自由基聚合可以导致低聚分散指数BA聚合物的产生。 因此，高温聚合提供了更好的可控性来生产所需的聚合物产品。该NSF Goali项目是Drexel University与Dupont之间的共同努力，旨在提高丙烯酸酯和苯乙烯，同源性，同源，同源物和共聚物的质量，并通过高温溶液溶液聚合产生。 这个行业的教职项目的动机是出于需要采用基本方法来提高产品质量的动机。 Pi Soroush将在杜邦的马歇尔实验室（Marshall Laboratory）呆一年，以进行以下研究和教育活动： *研究液相，高温（140-200oc）的动力学（140-200oc），自由基，BA和丁基甲基丙烯酸酯（BMA）（BMA）（BMA）（BMA），均质化反应，以开发用于高态模型的poligation Polymatization polymation polymation polymatization，BMA和BMA，BMA和BMA和BMA。 *计算最佳温度和进料流量率轮廓以及高温，半批量，BA和BMA的加载条件，聚合反应器。 *制定了一组工业，过程建模，开放式问题，将分配为本科生，以在Drexel University的过程建模课程中。
