    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 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. One print quality occurs in a draft mode, which is a relatively high speed, in which there is substantial conservation of the thermal transfer medium. The peel angle of the thermal transfer medium from a recording medium (12) on which printing occurs is maintained at a relatively low angle to increase the contact time between the thermal transfer medium and the recording medium.

    摘要： 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 groups; and benzylic groups with hydrogen atoms intramolecularly accessible to the carbonyl group(s) present in the radiation-activatable crosslinking agent; and n represents an integer of 2 or greater. Further disclosed are novel photocrosslinkers based upon 2,4,6-tri(4-benzoylphenoxy)-1,3,5-triazines.
