Abstract:
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.
Abstract:
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.
Abstract:
A composition includes a silyl hydride (having at least one silicon-bonded hydrogen atom per molecule) and a fluorinated triarylborane Lewis acid. In the method, the Lewis acid catalyzes reaction of siliconbonded hydrogen atoms from the silyl hydride and water, thereby forming a siloxane bond in the resulting product. The composition and method can be used to form siloxane intermediates and cured networks.
