摘要： Proceso para formar un microgel que comprende un núcleo de polímero reticulado y una pluralidad de brazos poliméricos prácticamente lineales unidos al núcleo, comprendiendo el proceso los pasos de: I) introducir monómero monoolefínico, catalizador e iniciador en un reactor en ausencia de monómero multiolefínico y producir un componente prepolímero activable B que tiene un peso molecular medio en peso de 1.000-25.000, comprendiendo dicho prepolímero activable un polímero que contiene grupos halógeno activado, un polímero terminado con grupos tiocarboniltio, o un macromonómero que tiene al menos una funcionalidad activa en polimerización; II) poner al producto de I) en contacto con monómero multiolefínico para producir el componente reticulado A y el componente soluble C, opcionalmente en presencia de iniciador adicional, y también opcionalmente en presencia de iniciador y monómero monoolefínico adicional; pudiendo la relación de componentes A/(B+C) ser controlada a base de variar la relaciónmolar de (Componente B)/(monómero multiolefínico) desde 0, 05/1 hasta 5/1, a base de disminuir dicha relación molar para incrementar la relación de A/(B+C), y a base de incrementar dicha relación molar para disminuir la relación de A/(B+C); teniendo el microgel un peso molecular medio en peso de 104 - 108.

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： This invention relates to a method for forming a multi-layer coating, comprising sequentially applying a primer surfacer, a basecoat, and a clear coat composition on an automotive substrate in a wet-on-wet-on-wet manner, and simultaneously curing the applied three layers together in a single baking step, wherein the primer surfacer comprises: a film forming binder, a volatile organic liquid carrier, and pigment(s); and the binder contains about: (a) about 30 to 80% by weight, based on the weight of the binder, of a hydroxyl functional polyester resin; (b) about 10 to 30% by weight, based on the weight of the binder, of a crosslinking agent selected from the group consisting of a melamine resin, a blocked polyisocyanate resin, or a mixture thereof; (c) about 10 to 40% by weight, based on the weight of the binder, of a dispersed graft polymer comprising a non-crosslinked core of acrylic polymer which is substantially non-soluble in non-polar organic solvent and, grafted to the core, one end of an acrylic stabilizer in the form of a macromonomer, said acrylic stabilizer being soluble in a non-polar organic solvent; wherein the composition is, preferably, essentially free of crosslinked nonaqueous dispersion resin particles or crosslinked microgel resin particles or both, and the composition also contains at least one non-polar organic solvent at the time of application. The resulting multi-layered coating film has excellent aesthetic appearance, chipping resistance, sag resistance, and film build even when formed in a three wet layered application method.
