    摘要： Aqueous dispersions having improved stability and which are particularly well suited for use as aqueous ink jet ink compositions comprise an aqueous carrier medium which comprises water or a mixture of water and at least one organic component; a particulate solid, preferably a pigment; and an ABC triblock polymer comprising an A block which is a hydrophilic polymer, a B block which is a polymer capable of binding to the particulate solid, a C block, different from the A and B block, which is a hydrophobic or hydrophilic polymer; and wherein the A and C blocks are end blocks.

    摘要： Method for patterning organic polymer layers comprising the sequential steps:A. Applying to a substrate an unpatterned layer of solid acid labile polymer;B. Applying to the unpatterned layer a patterned second layer comprising a liquid solution of organic acid and volatile solvent;C. Heating the patterned layer to effect removal of the volatile solvent from the layer and diffusion of the organic acid into the underlying areas of the first layer; andD. Washing the layers with aqueous base solution to remove the solubilized acid labile polymer from the patterned areas of the layers.

    摘要： Group Transfer Polymerization (GTP) process for preparing a "living" polymer, the process comprising contacting under polymerizing conditions in a polymerization medium, at least one acrylic or maleimide monomer with an initiator which is a tetracoordinate organosilicon, organotin or organogermanium compound having at least one GTP initiating site and a catalyst which is or is a source of an anion selected from the group consisting of bifluoride, fluoride, cyanide, azide or a selected oxyanion, or a selected Lewis acid or Lewis base, the process further characterized in that the initiator or the anion or Lewis acid catalyst is chemically attached (grafted) to a solid support that is insoluble in the polymerization medium.
