    • The present invention is directed to a thermally initiated polymerization process. The process provides for heating in a reactor a reaction mixture comprising one or more acrylate monomers to a polymerization temperature ranging from 120°C to 500°C, and polymerizing the reaction mixture into a polymer. Applicants made an unexpected discovery that acrylate monomers can be used as thermal initiators, which makes the process more economical than conventional thermally initiated polymerization processes. The reaction mixture can also include non-acrylate monomers. Several novel steps are also disclosed to control the molecular weight and the polydispersity of the resulting polymer are also disclosed. The polymers made by the low cost process of the present invention have wide application, such as in automotive OEM and refinish coating compositions.
    • 本发明涉及热引发聚合方法。 该方法提供在反应器中将包含一种或多种丙烯酸酯单体的反应混合物加热至120℃至500℃的聚合温度,并将反应混合物聚合成聚合物。 申请人发现了一个意外的发现,即丙烯酸酯单体可以用作热引发剂,这使得该方法比常规的热引发聚合方法更经济。 反应混合物还可以包含非丙烯酸酯单体。 也公开了几种新的步骤来控制所得聚合物的分子量和多分散性。 通过本发明的低成本方法制造的聚合物具有广泛的应用,例如在汽车OEM和修补涂料组合物中。
