  • Epoxy resin imbibed polymer particles
    Patent number: 10570272
    Abstract: The present invention relates to an aqueous polymer dispersion composition comprising a stable aqueous dispersion of single-phase thermoplastic polymer particles imbibed with a thermosettable compound having at least two oxirane groups. The thermoplastic polymer particles have a sufficient concentration of anti-agglomerating functional groups to stabilize the latex against agglomeration, and the thermoplastic polymer particles being a copolymerization product of a monomer mixture comprising, based on the total dry weight of the monomer mixture (a) 35 wt. % to 71 wt. % of ethyl acrylate, (b) 30 wt. % to 60 wt. % of methyl methacrylate, and (c) 5 wt. % to 10 wt. % methylol acrylamide.
    Type: Grant
