Cellulose cyanoacrylate is employed either to bond two surfaces or to duplicate the shape of a three-dimensional object. The method is carried out by applying a release material to the object to be duplicated, applying a sheet of cellulosic material formed of wood fibers onto the three dimensional object, then saturating the sheet of cellulosic material with a cyanoacrylate glue and permitting the saturated sheet to cure. The resulting product duplicates the shape of the object. Two surfaces may be bonded by placing a sheet of cellulosic material between the two surfaces and applying the cyanoacrylate glue to edges of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulosic material. This material may also be employed in bone or tooth repair. A break or fracture in an article can be repaired by positioning a sheet of cellulosic material over the break, saturating it with cyanoacrylate glue, and holding the saturated sheet in place with a releasable film.

Molecularly imprinted polymers (MIPs) are materials exhibiting molecular recognition of a target molecule. MIPs are synthesized in the presence of an aflatoxin template, a mimic to the targeted molecule, used as an imprint that is further washed away with suitable solvent after completion of the polymerization process, leaving a cavity in the polymer of the same stereochemistry, functionality and morphology to the template. When the MIP encounters an aflatoxin, the molecule is bound in the cavity with a receptor-like affinity.

The formation of microporous surfaces through polymer induced phase separation in a photopolymer solvent mixture using photopolymerization via light self-focusing and self-trapping. The self-trapping of light sets fixed regions of brightness and darkness, sustained by the polymerization of light, and then wave guiding within the substrate. Phase separation occurs with the solvent phase separating in the regions of darkness and crosslinking in the regions of brightness. Upon removal of the solvent, precise and uniformly dispersed pores are created in the surface. The pore size and spacing may be tuned by adjusting the weight fraction of the photopolymer solvent mixture as well as through changes in the mask pattern. 1.

A polymer-encapsulated pigment dispersion is prepared from a mixture of (a) a carrier; (b) pigment particles; and (c) a polymeric dispersing agent having a polymer backbone, and an alkali-swellable copolymer component. The dispersing agent may provide efficient pigment wetting and dispersion using relatively low and thus economical dispersant amounts, and subsequently enable formation of polymer-encapsulating pigment dispersions that, when used in coatings, provide good opacity and good hiding characteristics, especially in titanium dioxide-containing coating compositions.
