  • Patent number: 11597804
    Abstract: The present application is directed to a nanocomposite organo gel having a continuous polymeric network structure, wherein polymer chains are held together by ionic interaction between polymer chain ends, interparticle chain entanglements, layered silicate surface modifier, ionic salt, and layered silicate. The present application is also directed to methods of making and using the nanocomposite organo gel.
    Type: Grant

  • Patent number: 10532964
    Abstract: Herein disclosed is an economical standalone system that replaces conventional monomer purification methods needed to perform chemical reactions that require reactants with a high degree of purity. Chemical reactions, such as anionic polymerization, can produce highly monodisperse homopolymers and block copolymers, however to do so they require very high purity reactants along with a moisture and oxygen free atmosphere. The system and method uses traditional column purification methods, but incorporates them into an economical, standalone, compact, and hazard free system. This method is different in view of safety, cost of cleaning procedure, time commitment, space availability, design and operational ease; helping researchers save time by cutting down the operating commitment by 90% and most importantly making it safer.
