  • METHOD OF SYNTHESIZING POLAR WAXES AND POLYKETONES
    Publication number: 20260201085
    Abstract: A method of producing an oxidized form of waxes (polar waxes) or polyketones containing oxygen functional groups, which can be used as lubricants, adhesives, coating reagents, etc., from polypropylene (PP), polystyrene (PS) and/or polyethylene (PE). In one or more examples, a hydroperoxide was used as the oxidant to cleave C—C and C—H bonds at a mild temperature (e.g., 150° C.). C—C bond cleavage leads to a decrease in the number-averaged molecular weights (Mn) of polypropylene and polyethylene to 500-5000 g/mol. The method was successfully applied to the conversion of post-consumer polyolefin waste to make polar waxes or polyketones.

  • Clay activation of PD(II) and NI(II) complexes
    Patent number: 8268946
    Abstract: A clay-supported complex that includes a metal complex containing a phosphinobenzenesulfonate ligand coordinated to Pd(II) or Ni(II), and a clay combined with the metal complex. The metal complex can be neutral or charged. The clay-supported complex is active in the homopolymerization and copolymerization of olefins, including polarized and non-polarized alpha-olefins.
