摘要:Isosorbide-5-methacrylate was obtained by enzymatic catalysis with Lipozyme RM IM in a highly regioselective manner in up to 87% yield. The process uses readily available acyl donors (methacrylic anydride or vinyl methacrylate), is easily scalable and chromatography free. Simple extractive workup followed by decoloration and filtration affords the monomer with up to > 99% purity. In addition, the developed enzymatic strategy was applied for the synthesis of a series of isosorbide 5- and 2-methacrylate derivatives. All the sythesized isosorbide monomethacrylates were radically polymerized with AIBN. The properties of these polymers with different side groups in either endo or exo configuration in the isosorbide structure was examined. The methacrylic isosorbide derivatives with OH-group were found to have very high glass transition temperature (Tg = 167 °C) and good thermal stability (at 5% weight loss under N2, Td,95 = 240 °C). The highest molecular weight (Mn = 80.6 kg/mol) was determined for the polymethacrylate with Ac-substitute.

标题 :Synthesis of matte beads containing carboxylic acid and their use in photographic elements
发明人：SMITH DENNIS EDWARD; MUEHLBAUER JOHN LEONARD; WANG YONGCAI
摘要:The present invention is a process for making polymeric particles by reacting an ethylenically unsaturated monomer as a dispersed phase suspended in an aqueous phase. The aqueous phase contains a water-insoluble particulate stabilizer having a size less than 100 nanometers in an effective amount of water-soluble inorganic salt to allow formation of stable monomer droplets in the aqueous phase, the monomer droplets include at least 20% of a carboxylic acid-containing monomer. The present invention also provides an imaging element comprising a support and at least one layer containing polymer particles of the formula: (A) x (B) y , where A is ethylenically unsaturated monomer containing carboxylic acid groups, B is a water insoluble ethylenically unsaturated monomer, x is greater than 20% and y is equal to 100% minus x. The polymer particles are covered with a layer of water-insoluble solid particulate stabilizer having a size less than 100 nanometers.
