摘要： Functional gel particle formed from a crosslinked polymeric network including a fraction of stable crosslinks and a second fraction of cleavable crosslinks are disclosed. Functional compounds may be chemically or physically encapsulated within and/or released from the gel particle by selective cleavage of the cleavable crosslinks. The functional compounds may be delivered and released to a pre-selected target site. Peripheral or other accessible functionality on the surface of the gel particle allows attachment of a surface reactive agent, thereby modifying one or more surface properties of the gel particle. Processes of preparing the gel particles and processes of delivering the functional compounds to a target site are also disclosed.
摘要翻译：公开了由交联聚合物网络形成的功能性凝胶颗粒，所述交联聚合物网络包括一部分稳定的交联和第二部分的可切割交联。功能性化合物可以通过选择性切割可切割的交联物而化学地或物理地包封在凝胶颗粒内和/或从凝胶颗粒释放。功能性化合物可以被递送并释放到预先选择的靶位点。凝胶颗粒表面上的外周或其它可接近的官能团允许附着表面反应剂，从而改变凝胶颗粒的一种或多种表面性质。还公开了制备凝胶颗粒的方法和将功能性化合物递送至目标部位的方法。

摘要： The invention is directed to a microemulsion polymerization comprising adding a polymerization catalyst precursor, such as a transition metal complex in the higher of two accessible oxidation states, an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion. Radically polymerizable monomers and a reducing agent may then be added to the emulsion. The reducing agent converts the catalyst precursor to a catalyst for polymerization of the first monomer from the initiator. In certain embodiments the organic solvent may comprise radically polymerizable monomers. The aqueous solution may comprise a surfactant. Further embodiments are directed to an ah initio polymerization process comprising adding a polymerization catalyst precursor; an ATRP initiator, and an organic solvent to an aqueous solution to form an emulsion, wherein the organic solvent comprises second radically polymerizable monomers, adding a reducing agent to convert the catalyst precursor to a catalyst for polymerization of the first radically polymerizable monomer from the initiator; and adding first radically polymerizable monomers to the emulsion.

摘要： The present disclosure describes a two-step batch dispersion polymerization process for the preparation of substantially uniformed-sized functional (co)polymer particles. The first step of the process includes polymerizing at least one first radically (co)polymerizable monomer by a free radical polymerization process to form a (co)polymer in a stable colloidal dispersion and the second step includes polymerizing the at first radically (co)polymerizable monomer or an additional radically (co)polymerizable monomer in the stable colloidal dispersion by a living/controlled radical (co)polymerization process.
