Abstract: An acoustic imaging system coupled to a sensing plate to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers coupled to the sensing plate opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.

Abstract: The present invention relates generally to compositions prepared by polymerizing vinyl neo C9-C13 carboxylic acid esters. Such compositions include latex compositions that are formed by polymerizing vinyl neo C9-C13 carboxylic acid esters with ethylenically unsaturated comonomers such as acrylic acid esters and vinyl acetate. The polymer compositions of the present invention are particularly suitable for use in applications such as architectural (both interior and exterior), direct-to-metal and marine coatings and transportation maintenance applications.

Abstract: Acrylic copolymer PSA compositions having enhanced peel strength without substantially decreasing shear properties have been formulated by homogeneously incorporating the tackifying resin into the polymer matrix. The tackifying resin is dissolved into a solution of alkyl (meth) acrylate and (meth) acrylic acid monomers prior to polymerization. To enhance the molecular weight of the resultant PSA, the monomer/tackifier solution is emulsion polymerized in the absence of chain transfer agents, such as antioxidant additives typically found in commercially available tackifiers, and allylic hydrogen present in many unsuitable tackifiers.

Abstract: Acrylic copolymer PSA compositions having enhanced peel strength without substantially decreasing shear properties have been formulated by producing the copolymer with a broad molecular weight distribution such that the ratio M.sub.w /M.sub.n is above 6, preferably above 10. The alkyl (meth)acrylate and (meth)acrylic acid monomers are emulsion polymerized over a temperature profile wherein the difference between the maximum and minimum polymerization temperatures is at least about 40.degree. C. and less than about 70.degree. C., preferably using a redox initiator system such as bromate/bisulfite.

Abstract: Acrylic copolymer compositions which contain a tackifying hydrocarbon resin and a polyfunctional crosslinking monomer and the use of such composition in pressure-sensitive adhesives are described. The tackifying hydrocarbon resin is dissolved, as is the polyfunctional monomer, in a solution of alkyl(meth)acrylate and (meth) acrylic acid monomers and is present during the polymerization of the monomers to form a tackified acrylic copolymer.

Abstract: High solids content, high molecular weight hydrophobe-containing cationic polymer products are prepared by an inverse (water-in-oil) emulsion process wherein the hydrophobic monomer is in the water phase. The resultant polymers have increased activity in oily water clean-up.

Abstract: Hydrophobic water-insoluble monomers, such as alkyl acrylamides, which are solid at room temperature may be sufficiently dissolved in concentrated acrylamide or methacrylamide monomer solutions, in the absence of cosolvents, to allow copolymerization to occur without substantial phase separation. The hydrophobic monomer is added to the acrylamide monomer solution and heated, with agitation, to above the melting point of the hydrophobic monomer. Thereafter the temperature must be maintained at no lower than about 15.degree. C. below the melting point.

Abstract: There is disclosed a process for producing low energy vinyl dispersion resins which, in a plastisol, can be fused either at lower temperatures or in a shorter period of time than the normal dispersion grade resins presently employed. The new vinyl resin is characterized by being a bimodal resin, i.e., containing large particles and small particles of polymer in a predetermined size and amount. The small particles are a vinyl homopolymer or copolymer made by a regular emulsion polymerization procedure. The large particles are a vinyl copolymer made employing a seeded emulsion overpolymerization procedure wherein the seed is either a vinyl homopolymer or a vinyl copolymer. The final bimodal resin is obtained from a blend of the small and large particle latices by drying, such as spray drying, for example.
