AQUEOUS DISPERSION OF (METH)ACRYLIC POLYMER AND POLYSILSESQUIOXANE NANO PARTICLES
An aqueous dispersion containg (meth)acrylate polymer particles and substituted silsesquioxane-based particles dispersed in an aqueous carrier, wherein: (a) the substituted silsesquioxane-based particles have an volume-average size of 5 nanometers or more and at the same time less than 500 nanometers as determined by dynamic light scattering; and (b) the substituted silsesquioxane-based particles are substituted only with one or more than one moiety selected from a group consisting of alkyl, aryl, hydroxyl, trace amounts of alkoxy and combinations thereof and contain 50 mole-percent or less hydroxyl substitution in the form silanol functionalities relative to moles of substituted silsesquioxane-based particle as determined by infrared spectroscopy.
Iodine transfer radical polymerization of an ethylenically unsaturated monomer comprising (meth)acrylic acid, salt thereof, or combination thereof, in the presence of a radical polymerization initiator, an organoiodide, and a solvent, is a useful method for making (meth)acrylic acid polymers. The amounts of components utilized can be 2 to 100 equivalents of acrylic acid and 2 to 100 equivalents of sodium acrylate, both dissolved in water to form a 15 to 50 weight percent solution, based on the total weight of the acrylic acid, sodium acrylate, and water; 0.05 to 1 equivalent of an azo polymerization initiator, 1 equivalent of an organoiodide; and 0 to 3 equivalents of an iodide salt. (Meth)acrylic acid polymer solutions are made by these methods. The (meth)acrylic polymers are useful as dispersants.
A fire-resistant polyurethane composition and a fire-resistant product comprising the fire-resistant polyurethane composition. The fire-resistant polyurethane coating composition comprises: an aromatic isocyanate component, a polyol component, and an intumescent component; wherein the aromatic structure in the polyurethane backbone is =24wt%. The fire-resistant polyurethane composition could provide surprisingly good intumescent layer toughness as well as good insulation performance.
Reverse iodine transfer polymerization of an ethylenically unsaturated monomer comprising (meth)acrylic acid, salt thereof, or combination thereof, in the presence of a radical polymerization initiator, an oxidant, an iodide salt, and a solvent, is a useful method for making (meth)acrylic acid polymers. The amounts of components utilized can be 5 to 500 equivalents of the ethylenically unsaturated monomer comprising (meth)acrylic acid, salt thereof, or combination thereof, in the presence of 1 to 3 equivalents of the radical polymerization initiator, 0.2 to 1 equivalent of the oxidant, and 1 equivalent of the iodide salt. (Meth)acrylic acid polymer solutions are made by these methods. The (meth)acrylic polymers are useful as dispersants.
