    摘要： The invention provides in one aspect a process for preparing a microgel by RAFT polymerizing in the presence of a RAFT chain transfer agent, one or more solvophobic monomers and one or more solvophilic monomers to form one or more block copolymers comprising one or more solvophobic blocks and one or more solvophilic blocks wherein the solvophobic block is insoluble in a dispersing medium and the solvophilic block is soluble in the dispersing medium. The block copolymer is dispersed in the dispersing medium to form micelles, which is then stabilized to form the microgel. The dispersing medium can be aqueous or lipophilic. The method of the present invention also permits one to encapsulate a wide variety of materials, such as pigments, dye molecules, and aluminum flakes used in metallized paints.

    摘要翻译： 本发明在一个方面提供了一种通过RAFT聚合制备微凝胶的方法，其在RAFT链转移剂，一种或多种疏水单体和一种或多种溶剂亲油性单体的存在下聚合以形成一种或多种包含一种或多种疏乳嵌段的嵌段共聚物和 一种或多种溶剂亲和性嵌段，其中所述疏水性嵌段不溶于分散介质，并且所述溶剂性嵌段可溶于所述分散介质中。 将嵌段共聚物分散在分散介质中以形成胶束，然后将其稳定化以形成微凝胶。 分散介质可以是水性或亲油性的。 本发明的方法还允许包封各种材料，例如用于金属化涂料中的颜料，染料分子和铝薄片。
