    摘要: 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.

    摘要: A process for preparing a sign that includes the steps of providing a sheet of material; defining on a surface of the sheet a series of image-bearig areas and non-image-bearing areas; treating the surface of the sheet with an essentially solvent-free composition comprising a colorant and a polymeric binder to selectively deposit the composition on the non-image-bearing areas of the surface of the sheet; and fusing the composition to create a continuous polymer film on the non-image-bearing areas.
