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.

摘要:A technique of improving the hydrogenation reaction of diene-based polymers, present in aqueous suspension, by in-situ synthesizing the catalyst in the presence of a specific aliphatic alcohol is disclosed. The process allows the selective hydrogenation of the carbon-carbon double bonds in the diene-based polymers with a high degree of hydrogenation and short reactions times. The improved process eliminates the complicated catalyst synthesis operations so far necessary.

摘要:Provided are new functionalized nitrile rubbers, which may optionally also be in partially or wholly hydrogenated form, and also a process for preparing them by metathesis of nitrile rubbers in the presence of a metathesis catalyst and at least one functionalized allyl compound. The new functionalized nitrile rubbers are suitable for producing vulcanizable mixtures and allow the production of vulcanizates having very stable networks. Also made possible, in particular, is the synthesis of block copolymers.
