Abstract: A protective film includes a base layer and a wear layer, the wear layer comprising a UV cured hardcoat resin, and the UV cured hardcoat resin comprising surface modified silica nanoparticles. The protective film may comprise a pressure sensitive adhesive for adhesion to a floor. The protective film may be used, for example, as a protective floor finish.

Abstract: The invention features protective film constructions that may be used, for example, as a protective floor finish.

Abstract: A pressure sensitive adhesive composition comprised of: a) 75 to 99.9 weight percent of a tackified thermoplastic polymer component comprising 1) 1–99 weight percent of a thermoplastic polymer substantially without epoxy-binding or ester functions, and 2) 1–99 weight percent of a tackifier; and b) 0.1 to 25 weight percent of an epoxy component comprising a cured epoxy and non-woven webs made of this adhesive composition.

Abstract: Radiation-crosslinkable elastomeric compositions containing: (a) an elastomeric polymer containing abstractable hydrogen atoms in an amount sufficient to enable the elastomeric polymer to undergo crosslinking in the presence of a suitable radiation-activatable crosslinking agent; and (b) a radiation-activatable crosslinking agent of the formula: wherein: X represents CH3—; phenyl; or substituted-phenyl; or substituted-phenyl with the proviso that any substituents on the substituted-phenyl do not interfere with the light-absorbing capacity of the radiation-activatable crosslinking agent and do not promote intramolecular hydrogen abstraction of the radiation activatable crosslinking agent; W represents —O—, —NH—, or —S—; Z represents an organic spacer selected from the group consisting of aliphatic, aromatic, aralkyl, heteroaromatic, and cycloaliphatic groups free of esters, amides, ketones, urethanes, and also free of ethers, thiols, allylic grou

Abstract: Microspheres comprise a polymer including one or more of 1) a plurality of C3 or larger alpha-olefin units wherein the C3 or larger alpha-olefin units are incorporated into the polymer so as to give an average number of less than one branch point per C3 or larger alpha-olefin unit, 2) a plurality of C2 alpha-olefin units wherein the C2 alpha-olefin units are incorporated so as to give an average number of branch points greater than 0.01 per C2 alpha-olefin unit, and 3) cyclopentene or substituted cyclopentene, the microspheres having an average diameter in the range of 1 to 300 micrometers. Optionally, the polymer of the microspheres can be crosslinked. The microspheres can be prepared by suspension or dispersion polymerization processes using aqueous or organic reaction media. Powder coatings can be prepared from the microspheres.

Abstract: A polymerizable composition comprises an alpha-olefin hydrocarbon monomer, an effective amount of an organometallic catalyst of a Group VIII metal, preferably Ni or Pd, and at least one of water and air. Novel catalysts for polymerizing alpha-olefin hydrocarbon monomers provide improved processes and products. Methods of the invention include polymerizing the composition in open air and in the presence of water to provide novel polymers.

Abstract: Various catalyst precursors are used for the thermal decomposition of azide-containing polymers and oligomers. The catalyst precursors are organometallic complexes which upon thermolysis are capable of liberating at least one coordination site, thereby generating a catalyst for the thermal decomposition of the azide-containing polymer or oligomer.

Abstract: A thermal printer (10) has a thermal transfer medium (28) fed past a thermal printhead (21) at a substantially constant velocity by a feed roll (82) engaging the thermal transfer medium just prior to the printhead to maintain a portion of the thermal transfer medium between the printhead and the feed roll relatively stiff. The feed roll is mounted on a cartridge (30) having the thermal transfer medium supplied therefrom. A drag brake (70) is disposed in the feed path of the thermal transfer medium prior to the feed roll to cause a substantially constant premetering tension to be applied to the thermal transfer medium irrespective of the coefficient of friction between the drag brake and the thermal transfer medium. A carrier (14), which supports the printhead and a feed roll driver (90), is driven separately from the feed roll driver so that various ratios between the velocities of the thermal transfer medium and the carrier are obtained to produce various print qualities.
