摘要： The invention provides compositions of matter, methods of their synthesis, and methods of their use in polymerization reactions. The compositions include polyfunctional initiators used to make star polymers when polymerized with monomers. The polyfunctional initiators are synthesized out of a multifunctional core with at least two functional groups and two or more initiator units bonded to the functional groups. The initiator units have two electron-withdrawing groups bonded to a central carbon atom and an azo group between the central carbon atom and the functional group. The polyfunctional initiators are particularly effective because when they decompose to form the radical core of a star polymer, the electron-withdrawing groups prevent the corresponding radical from forming any linear polymer contamination and only desired star polymers result. In addition when the desired star polymers are fed into a reaction vessel by streams with two different concentrations the star polymers produce superior properties.
摘要翻译：本发明提供了物质组合物，其合成方法及其在聚合反应中的应用。组合物包括当用单体聚合时用于制备星形聚合物的多官能引发剂。多功能引发剂由具有至少两个官能团的多官能核心和与官能团结合的两个或更多个引发剂单元合成。引发剂单元具有与中心碳原子键合的两个吸电子基团和中心碳原子和官能团之间的偶氮基团。多官能引发剂是特别有效的，因为当它们分解形成星形聚合物的自由基核心时，吸电子基团阻止相应的自由基形成任何线性聚合物污染，并且仅产生所需的星形聚合物。此外，当所需的星形聚合物通过具有两种不同浓度的物流进入反应容器时，星形聚合物产生优异的性能。

摘要： Disclosed and claimed is a method for improving the froth quality and bitumen recovery in primary bitumen extraction processes by coagulant addition in the underwash feed water. Preferred coagulants are cationic or amphoteric polymers. Coagulant addition in the underwash feed water reduces the solids content reporting to the primary bitumen froth in a primary separation vessel (PSC). This treatment program can also be combined with dispersant addition in the dilution make-up feed water into a PSC. Preferred dispersants are low molecular weight anionic polymers.
摘要翻译：公开并要求保护的是通过在洗涤水中加入凝结剂来提高初级沥青提取过程中的泡沫质量和沥青回收率的方法。优选的凝结剂是阳离子或两性聚合物。在洗涤进料水中的凝结剂添加减少了在初级分离容器（PSC）中报告给主要沥青泡沫的固体含量。该处理程序也可以与稀释补充剂中的分散剂添加到PSC中。优选的分散剂是低分子量阴离子聚合物。
