  • High productivity bisphenol-a catalyst
    Publication number: 20020123534
    Abstract: A high productivity catalyst for bisphenol-A has been discovered which comprises strongly acidic cation-exchange resin spheres produced from a polystyrene/divinylbenzene (PS/DVB) copolymer sulfonated under conditions to introduce sulfone cross-linking. Surprisingly, the sulfone cross-linking improves the resistance to deformation but does not have a negative effect on the activity and selectivity of the catalyst in bisphenol-A production.

  • Hydrozirconated matrix and process for polyolefin production
    Publication number: 20020052536
    Abstract: A hydrozirconated matrix for the production of polyolefins is disclosed. The hydrozirconated matrix is prepared from the reaction of an organozirconium composition and an olefin based material. A process is described for using the hydrozirconated matrix to prepare a range of polyolefin products.

  • High surface area adsorbents and method of preparation
    Patent number: 6235802
    Abstract: A process for the preparation of high surface area, low-swelling macroporous polymeric adsorbents is disclosed. The use of organic sulfonic acids to provide postcrosslinking of macroporous copolymers eliminates the need for traditional organic swelling solvents and Lewis-acid catalysts used to provide conventional macronetted polymers. In particular, methanesulfonic acid provides macroporous polymeric adsorbents having high surface area and porosity, low levels of residual vinyl groups, and free of residual contaminants from conventional Lewis-acid/Friedel-Crafts reactions.

  • Decolorization of sugar syrups using functionalized adsorbents
    Patent number: 5972121
    Abstract: A process for decolorizing sugar solutions by contacting them with highly crosslinked, macroporous copolymers functionalized with weak-acid or weak-base ion exchange functional groups is disclosed. Treatment of sugar syrups using macroporous functionalized adsorbents allows for multiple regeneration cycles without loss of sugar decolorization properties.
