    Abstract: A process including the steps of: providing a planetary roller extruder having a plurality of compounding sections including a main spindle surrounded by and intermeshed with a plurality of planetary spindles; introducing monomers and initiator into a first compounding section; producing a homogeneous composition; heating the composition to initiate free-radical polymerization; introducing monomers and initiator into one or more of the remaining compounding sections and continuing the polymerization; discharging the polymerized composition; and optionally, taking a portion of the composition discharged from the planetary roller extruder and returning it to the first compounding section.

    Abstract translation: 包括以下步骤:提供具有多个复合部分的行星式辊挤出机,所述复合部分包括由多个行星轴包围并与其相互啮合的主轴; 将单体和引发剂引入第一混合部分; 产生均匀的组合物; 加热组合物以引发自由基聚合; 将单体和引发剂引入一个或多个剩余的混合部分并继续聚合; 排出聚合的组合物; 并且任选地从行星式辊挤出机中取出一部分组合物并将其返回到第一混合部分。
