摘要：
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.
摘要（中）：
本发明涉及一种热引发聚合方法。 该方法提供在反应器中加热包含一种或多种丙烯酸酯单体的反应混合物至聚合温度为120℃至500℃，并将反应混合物聚合成聚合物。 申请人意外地发现丙烯酸酯单体可以用作热引发剂，这使得该方法比常规热引发聚合方法更经济。 反应混合物还可以包括非丙烯酸酯单体。 还公开了几个新颖的步骤来控制分子量，并且还公开了所得聚合物的多分散性。 通过本发明的低成本方法制备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。
