  • High solids content dendrimer polymer composition
    Patent number: 10400132
    Abstract: The present invention relates to a polymer composition comprising: (i) one or more dendritic polymers; and (ii) a reactive diluent that is capable of being chemically coupled to the functional groups of the dendritic polymers, wherein when the dendritic polymer is coupled to the reactive diluent in the presence of a cross-linker, a polymerized solid is formed at high concentrations in a liquid medium. The present invention further relates to methods of preparing the polymer composition and its use in forming coatings.
    Type: Grant

  • Water dispersible hyperbranched polymer composition
    Patent number: 10160836
    Abstract: There is provided a composition comprising: (i) a hyperbranched polymer having peripheral reactive groups comprising epoxy functional groups and hydroxyl functional groups; and (ii) a compound having one or more hydrophilic functional groups, wherein the amount of epoxy functional groups relative to the total number of peripheral reactive groups does not render the hyperbranched polymer from being indispersible in an aqueous solvent. There is also provided a method of preparing the same and uses thereof.

  • Aqueous dispersible polymer composition
    Patent number: 9663680
    Abstract: The present disclosure relates to an aqueous dispersible polymer composition comprising: (a) at least one of: (i) a dendritic polymer in admixture with a hydrophilic functionalizing agent; and (ii) a hydrophilic functionalized dendrimer; and (b) a non-dendritic polymer capable of forming bonds with said dendritic polymer to thereby form a dendrimer-non-dendrimer (DND) polymer hybrid that is dispersible in the aqueous phase, methods of forming the same and uses thereof.
