  • Patent number: 8367598
    Abstract: This invention relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. The whitening agents are further characterized by having a dispersion component value of the Hansen Solubility Parameter of less than or equal to about 17 MPa0.5. This invention also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.

  • Patent number: 8273829
    Abstract: The present disclosure relates to a method for making a conjugated polymer. In the method, polyacrylonitrile, a solvent, and a catalyst are provided. The polyacrylonitrile is dissolved in the solvent to form a polyacrylonitrile solution. The catalyst is uniformly dispersed into the polyacrylonitrile solution. The polyacrylonitrile solution with the catalyst is heated to induce a cyclizing reaction of the polyacrylonitrile, thereby forming a conjugated polymer solution with conjugated polymer.
