  • Publication number: 20200131318
    Abstract: Lignin pellets comprising fused lignin are described herein. The lignin pellets may further comprise a processing aid, and/or a surfactant, and/or a chemical modifying agent, and/or a compatibilizer and/or a thermoplastic polymer. An extrusion process for producing the lignin pellets and their use in the manufacture of lignin thermoplastic blend products, polyols, polyphenols, polyaromatics and polyurethanes is also disclosed herein. The extruded lignin pellet may be dry-blended with additional thermoplastic and/or additive and then directly processed using processes such as injection molding, compression molding, extrusion, extrusion coating, blowing, thermoforming, stamping, foaming, fiber drawing, calendering or rolling.

  • Patent number: 9175147
    Abstract: A new approach for improving fire resistance of cellulosic materials is provided, especially when the cellulosic material is to be used in polymer composites. Cellulosic material is treated with an aqueous mixture of alkali metal or ammonium hydroxide and alkaline earth or aluminum metal salt simultaneously with or within a short period of time of preparing the mixture. The treated cellulosic material becomes self-extinguishing and may also have improved thermal stability, improved interfacial thermal resistance, improved resistance to damage by oxidants and other chemical agents, improved resistance to biological agents and/or improved resistance to damage by ultra-violet light.

  • Patent number: 8227527
    Abstract: A method comprising preparing a solution of clay particles solution, submitting the solution of clay particles first to a high pressure and high velocity flow for shearing the particles in the solution of clay particles, and to a sudden lower pressure, whereby the particles explode into the mist of the solution of clay particles, and mixing the finely dispersed clay solution, whereby epoxy is introduced in the solution of clay particles during on of the above steps of preparing the solution of clay particles or dispersing the solution of clay particles or to the resulting dispersed solution of clay particles, yielding an extremely fine and homogeneous distribution of the particles of nanodimensions in the epoxy, yielding a high-performance nanocomposite epoxy.

  • Publication number: 20080207801
    Abstract: A polymer nanocomposite contains layered clay dispersed in a polymer matrix together with compatibilizers for the clay and polymer matrix. The compatibilizers are a combination of two or more graft polymers. One graft polymer has high functionality and short chain length and another graft polymer has low functionality and long chain length. Such polymer nanocomposites have improved dispersion and better strength and modulus, while maintaining good toughness and impact strength. The polymer nanocomposites are particularly useful in applications where good mechanical performance and light-weight are of importance.
