  • MELT DISPERSION PROCESS FOR MAKING POLYMER POLYOLS
    Publication number: 20230242757
    Abstract: A preformed thermoplastic polymer is dispersed into a polyol via a mechanical dispersion process. A stabilizer is present to stabilize the dispersed polymer particles. An antisolvent is also present. The antisolvent has been found to lead to smaller particle size and increased dispersion stability.

  • Coating compositions
    Patent number: 11401425
    Abstract: The present disclosure provides for an aqueous dispersion for use in coating applications. The aqueous dispersion includes an aqueous composition and a solid content of a melt blend product having an acid functionalized polypropylene base polymer, a polypropylene copolymer, an acid functionalized polypropylene wax and an acid functionalized polyolefin. The aqueous dispersion is included in a coating composition, where the coating composition includes the aqueous dispersion, a solvent, a crosslinker and a basic water composition having water and a base. The present disclosure also provides for a coated article having a substrate and a coating on the substrate, where the coating includes the coating composition of the present disclosure.
