Friction-activated adhesive formulations and application devices

The present disclosure provides an aqueous dispersion. The aqueous dispersion includes a) water; b) a surfactant having at least one ethylenically unsaturated group; and c) polyester particles dispersed in the water. The polyester particles include a water-insoluble polyester having a weight average molecular weight of 20 kiloDaltons or greater, and the polyester particles have an average diameter that is submicron in size. Further, the present disclosure provides a method of making the aqueous dispersion. The method includes a) dissolving a water-insoluble polyester in a water-immiscible solvent to form a polyester solution; b) combining the polyester solution with an aqueous solution including water and a surfactant; and c) removing at least a portion of the water-immiscible solvent to form the aqueous dispersion including polyester particles dispersed in the water. The present disclosure also provides a photopolymerizable composition including a) water; b) a surfactant; c) polyester particles dispersed in the water; d) a photoinitiator; e) at least one ethylenically unsaturated monomer dispersed in the water; and f) an optional polymerization inhibitor. The present disclosure also provides coatings and articles prepared from the aqueous dispersion or photopolymerizable composition.

Aqueous dispersions including polyester particles, photopolymerizable compositions, articles, and methods

A method for building three-dimensional articles using a thermal polymerization process in provided. The articles are built by using a composition that includes a thermally polymerizable composition, a thermal initiator, and a nonlinear light-to-heat conversion material such as a reverse saturable dye. The article is built by the sequential exposure of adjacent voxels with a laser beam. Microlens arrays can be used to expose more than one voxel at a time.

Three-dimensional articles using nonlinear thermal polymerization

Composite layer comprising a plurality of longitudinal first zones comprised of a first polymeric material alternating with a plurality of longitudinal second zones comprised of a second polymeric material such that one first zone is disposed between two adjacent second zones. The zones are generally parallel to one another, and at least one of each first zone or each second zone has a maximum width dimension of not greater than 2 mm. Adjacent first and second zones have an average pitch, wherein for the composite layer there is an average of said average pitches, and wherein the average pitch for any adjacent first and second zones is within 20 percent of the average pitch for adjacent first and second zones of said average of said average pitches.

Composite layer

A copolymer comprises the reaction product of (a) (meth)acrylate functionalized nanoparticles, (b) vinyl monomer, and (c) mercapto-functional silicone. The (meth)acrylate functionalize nanoparticles are selected from the group consisting of silica nanoparticles, zirconia nanoparticles, titania nanoparticles, and combinations thereof.

Copolymers of nanoparticles, vinyl monomers and silicone

A copolymer comprises the reaction product of (a) (meth)acrylate functionalized nanoparticles, (b) vinyl monomer, and (c) silicone macromer. The (meth)acrylate functionalize nanoparticles are selected from the group consisting of silica nanoparticles, zirconia nanoparticles, titania nanoparticles, and combinations thereof.

The present invention provides an adhesive made from a reaction product of: (a) a polymerizable monomer derived at least in part from non-petroleum resources; (b) an initiator; (c) a polymeric stabilizer, wherein the reaction occurs in water to yield a microsphere adhesive. The microsphere adhesive can be formulated into a pressure sensitive adhesive composition that can be applied to various substrates such as paper and polymeric film to produce repositionable adhesive coated articles such as tapes, notes, flags, easels and the like.

Microsphere pressure sensitive adhesive composition

An adhesive blend includes a pressure sensitive adhesive and non-tacky microspheres that function as a detackifier. The non-tacky microspheres are solid, elastomeric, non-crushable, and solvent insoluble. The non-tacky microspheres are a reaction product of at alkyl (meth)acrylate monomers having from 1 to 14 carbon atoms, multifunctional (meth)acrylate and or multifunctional vinyl crosslinker, initiator, and polymeric stabilizer. The blend can be coated onto a sheet to form a pad, such as an easel pad.
