  • Ink receptor media suitable for inkjet printing
    Patent number: 6096469
    Abstract: The ink receptor media of the invention comprise an ink receptor comprising surfactant templated mesoporous particles dispersed within an organic binder on the substrate. The ink receptor media may also have an ink fixing material within or on the ink receptor. The invention also describes surfactant templated silica particles having a narrow particle size distribution and having intraparticle pore sizes of about 1.5 to about 10 nm and methods of preparing said particles. The invention also describes a colloidal dispersion of STM particles methods of making said dispersions.

  • Miscible polyolefin blends
    Patent number: 5955546
    Abstract: The invention relates to melt-miscible polyolefin blends, and a process for preparing the melt-miscible blends, of two or more polyolefins. Matching, within defined limits, the segment length of a modifying polyolefin with the segment length of a primary polyolefin, such as polypropylene or an ethylene/alpha-olefin copolymer, provides blends of the "matched" components which blends were heretofore unknown to be melt-miscible. A broad range of polyolefin blend compositions, and of polyolefin blends containing other polymers made compatible or dispersible with the polyolefin blend compositions, are defined, all of the blend compositions having at least one melt-miscible polyolefin phase.
