  • Publication number: 20250002743
    Abstract: The present invention relates to a multistage radical emulsion polymerization process for producing a knot scaling polymer dispersion of discrete particles dispersed in water, a polymer dispersion of discrete particles dispersed in water obtained by said process, and the use of said polymer dispersion as an indoor and outdoor coating composition for wood substrates or any wood-based material in order to prevent knot bleeding.

  • Patent number: 12098295
    Abstract: The present invention relates to a polymodal polymer composition having homogeneous as well as heterogeneous particles formed by radical emulsion polymerization of monomers from category A which forms homopolymers with Tg above 15° C. and monomers from category B which forms homopolymers with Tg below ?15° C. The polymer composition is composed of at least two different populations of particles, differing in mean particle size value by at least a factor of 2. Thus, the two different populations of polymer particles in the polymer composition differ with respect to size and monomer composition of the particles.

  • Publication number: 20230312766
    Abstract: The present invention relates to a multistage radical emulsion polymerization process for producing a polymer dispersion of discrete particles dispersed in water, thereby producing a novel star shaped polymer composition, where the wet and dry properties of the dispersion polymer obtained by radical emulsion polymerization in water are modified. The present invention also relates to its use in coating, textile and adhesive applications.
