  • Patent number: 5376509
    Abstract: A processing chemical for light-sensitive silver halide photographic material, comprising a cyclodextrin compound, which can contribute a decrease in packaging materials, transportation cost and storage space, can be free from lateral cracking at the formation of tablets, and can bring about an improvement in storage stability after being formed into processing solutions (i.e., more free from occurrence of stain during developing and scratches in light-sensitive materials having been processed, caused by deposition of crystals).

  • Patent number: 5274106
    Abstract: A vulcanizable elastomeric compound and products such as pneumatic tires and the like, are formed from a functionalized polymer having a functional group derived from an anionic polymerization initiator. The anionic polymerization initiator comprises the general formula ##STR1## where R.sup.1 -R.sup.5 are the same or different and are selected from the group consisting of hydrogen; alkyls having from alkyls having from 1 to about 12 carbon atoms; aralkyls having from 7 to about 20 carbon atoms; dialkylaminos having from 2 to about 20 carbon atoms; and, dialkylaminoalkyls having from 3 to about 20 carbon atoms. At least one of R.sup.1 -R.sup.5 is selected from the group consisting of the dialkylaminos and the dialkylaminoalkyls. Methods of the present invention include preparing functionalized polymers and reducing the hysteresis of vulcanizable elastomeric compounds.

  • Patent number: 5066721
    Abstract: There is a tire having tire performances such as wear resistance, cut resistance, heat build-up and the like and a processability simultaneously and economically improved by the application of a rubber composition containing a rubbery polymer modified with a silane compound and silica. The rubbery polymer modified with the silane compound is obtained by reacting an active terminal of a living polymer, which is obtained by polymerizing a monomer in the presence of an organic alkali metal catalyst, with a silane compound represented by the following general formula:X.sub.n Si(OR).sub.m R'.sub.4-m-n(where X is a halogen atom selected from a chlorine atom, a bromine atom and an iodine atom, OR is a non-hydrolyzable alkoxy group having a carbon number of 4.about.20, an aryloxy group or a cycloalkoxy group, R' is an alkyl group having a carbon number of 1.about.20, an aryl group, a vinyl group or a halogenated alkyl group, m is an integer of 1.about.4, n is an integer of 0.about.2, and a sum of n and m is 2.about.
