  • Publication number: 20240301630
    Abstract: The present disclosure describes methods of treating fibrous cellulosic materials with sucrose fatty acid ester containing particles (carrier systems) that allow for modifications of surfaces, including making such surfaces water resistance and/or oil/grease resistance. The methods as disclosed provide combining at least one saccharide fatty acid esters (SFAE) with a polymer (e.g., latexes) to form micellular particles and applying such particles to substrates including fibrous cellulose-based materials (e.g., pulp) to form, inter alia, molded products. Compositions comprising combinations of SFAE, a latex and optionally a mineral or other additives are also disclosed.

  • Patent number: 12018435
    Abstract: The present disclosure describes acyl halide liquid dispersions and tunable methods of treating cellulosic materials with compositions that provide increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for reacting acyl halides with and binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

  • Patent number: 11732127
    Abstract: Disclosed are processes for making polymeric composite materials and composite materials made from those processes, the process comprising: providing a mixture, comprising: a liquid, a polymer precursor, and a dispersed-phase precursor; and subjecting the mixture to reaction conditions sufficient: to effect polymerization of the polymer precursor to produce a polymer and a reaction product; and to remove substantially all the liquid and reaction product from the mixture; wherein said reaction conditions comprise: pressure between about 10 millitorr and about 300 torr; and temperature: greater than or equal to the highest boiling point of the liquid and reaction product; less than the decomposition temperature of the polymer; and less than the decomposition temperature of the dispersed-phase precursor.

  • Publication number: 20220267960
    Abstract: The present disclosure describes methods of treating cellulosic materials with barrier coating compositions that allow for modifications of surfaces, including making such surfaces exhibit barrier functions such as oil and grease resistance, water resistance and the like. The methods as disclosed provide combining at least one saccharide fatty acid ester (SFAE) with polymers and applying such combinations on substrates including cellulose-based materials. Compositions comprising combinations of SFAE and polymers are also disclosed, including the use of such compositions to reduce blocking effects of said polymers without affecting the barrier performance or folding of articles of manufacture coated with said compositions. In addition, blocking ratings data for SFAE-polymer compositions may be used to identify conditions under which adhesive properties may be exploited to produce compositions that allow for effective heat sealing of articles of manufacture.
