  A process is provided for the free radical polymerization of monomers derived from substituted or unsubstituted acrylic acid/methacrylic acid and esters thereof for the production of a polymer having a narrow molecular weight distribution and an average molecular weight of less than 4000. These polymers are produced by the solution polymerizing of said monomers wherein 20-40% by weight of the monomer composition is hydroxyalkyl acrylate or methacrylate in the presence of a solvent system suitable for high solids coating applications and in the presence of an initiating amount of a tertiary alkyl hydroperoxide and/or its derivatives having at least 5 carbons wherein the initiator and monomers, alone or in combination, are added continuously at a programmed rate wherein the rate of addition corresponds approximately to the rate of decomposition of said monomer and initiator. These polymers are used for high solids coating applications.

  本发明提供了一种单体的自由基聚合工艺，该单体来源于取代或未取代的丙烯酸/甲基丙烯酸及其酯类，用于生产分子量分布窄且平均分子量小于 4000 的聚合物。这些聚合物是通过上述单体的溶液聚合制得的，其中单体组合物重量的 20-40% 是丙烯酸羟烷基酯或甲基丙烯酸酯，在适用于高固体份涂料应用的溶剂系统存在下，以及在具有至少 5 个碳的叔烷基过氧化氢和/或其衍生物的引发量存在下，引发剂和单体（单独或组合）以编程速率连续添加，添加速率大致相当于上述单体和引发剂的分解速率。这些聚合物可用于高固体份涂料。
