    Abstract: Methods for preparing waterborne heat seal coating compositions are disclosed, including (A) melt blending an ethylene vinyl acetate copolymer, a tackifier, and a wax in a first mixing apparatus to form a melt blend, (B) contacting the melt blend with an initial aqueous stream comprising a neutralizing agent, water, and a surfactant in an emulsification zone of the second mixing apparatus to form a dispersion, and (C) diluting the dispersion with water in a dilution zone of the second mixing apparatus to form the waterborne heat seal coating composition. Methods for preparing waterborne heat seal coating compositions are also disclosed, including (A) melt blending an ethylene vinyl acetate copolymer, a tackifier, and a wax in a mixing and conveying zone of a mixing apparatus to form a melt blend, (B) contacting the melt blend with an initial aqueous stream comprising a neutralizing agent, water, and a surfactant in an emulsification zone of the mixing apparatus to form a dispersion, and (C) diluting the dispersion with water in a dilution zone of the mixing apparatus to form the waterborne heat seal coating composition, wherein the length-to-diameter ratio of the extruder mixing apparatus is greater than or equal to 12 to 1. Waterborne heat seal coating compositions prepared according to the disclosed methods are also disclosed.

    Abstract: The present invention provides methods for making polymerizable monomer compositions comprising purifying a (b) monomer mixture of (i) one or more monomers having at least two polymerizable vinyl groups and (ii) one or more monomers having a single polymerizable vinyl group as part of a (meth)acrylate ester group by any one or more of treating the monomer mixture in an activated porous alumina or silica column, sieve drying the monomer mixture in a vacuum followed by drying over dried molecular sieves having average pore sizes of from 2 to 20 Angstroms, freeze-pump-thaw (FPT) treating by freezing the monomer mixture in a vessel or container to a temperature below −75° C., degassing the monomer mixture by application of vacuum in the range of 102 to 10−2 Pa, sealing the vessel or container under vacuum, and thawing the composition to room temperature; and, combining in an inert gas atmosphere the resulting monomer mixture (b) with a composition (a) of quantum dots in dry form or organic solvent solution.
