Abstract:
A pressure sensitive adhesive composition is described comprising at least 50 wt-% of polymerized units derived from alkyl meth(acrylate) monomer(s); and 0.2 to 15 wt-% of at least one crosslinking monomers comprising a (meth)acrylate group and a C 6 -C 20 olefin group, the olefin group being optionally substituted. In another embodiment, an adhesive composition is described comprising a syrup comprising i) a free-radically polymerizable solvent monomer; and ii) a solute (meth)acrylic polymer comprising polymerized units derived from one or more alkyl (meth)acrylate monomers; wherein the syrup comprises at least one crosslinking monomer or the (meth)acrylic solute polymer comprises polymerized units derived from at least one crosslinking monomer, the crosslinking monomer comprising a (meth)acrylate group and a C 6 -C 20 olefin group, the olefin group being optionally substituted. In yet other embodiments, methods of preparing adhesive compositions are described
Abstract:
Processing tapes have special properties to permit them to be used to prepare laminate articles, such as security articles. The processing tapes include a backing, a pressure sensitive adhesive layer and a release surface covering the pressure sensitive adhesive layer. The backing is a dimensionally stable transparent polymeric film, and the surface on which the pressure sensitive is coated may be a treated surface. The pressure sensitive adhesive is a transparent pressure sensitive adhesive that includes a crosslinked (meth)acrylate-based polymer and has a refractive index in the range of 1.45-1.55. The (meth)acrylate -based polymer includes alkyl (meth)acrylate monomers and may include acidic monomers.

Photoiniferters for controlled radical polymerizations are described. The photoiniferters have a ring-opened azlactone moiety to provide telechelic (co)polymers.
Abstract:
Initiators for nitroxide-mediated radical polymerizations are described. The initiators have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.
Abstract:

Abstract:
The present invention provides crosslinkable compositions useful in the preparation of hydrophilic gels, and are prepared from oligomers having pendent hydrophilic poly(alkylene oxide) groups, and pendent polymerizable functional groups, and crosslinked by polyfunctional poly(alkylene oxides).
Abstract:
A gel material and medical articles including such material, wherein the transparent gel material includes a polymerized poly(alkylene oxide) macromonomer that, prior to polymerization, is free-radically polymerizable, multifunctional (preferably difunctional), and has an average molecular weight of at least about 2000.
Abstract:
The applicant relates to a polarizer and a precursor therefore. The precursor comprises a vinylalcohol polymer and a thermal acid generator such as a vinylchloride polymer or a chlorotriazine. The claimed precursor is supposed to undergo a transition upon irradiation and heating to chemically Form a polyvinyl alcohol/polyacetylene copolymer that serves a polariser.
