  • Patent number: 6562767
    Abstract: A lubricant for wire, which is insulated by means of a lacquer coating, and which is used for forming the stator windings of an electrical refrigerating compressor, consists of one or more compounds of the formula CH3—Xn—R, wherein X is a linear or branched hydrocarbon group with n carbon atoms, wherein n is up to 22, and R may be hydrogen or a plurality of different radicals, either in a pure form or dissolved in a suitable solvent. The lubricant is applied to the wire to reduce its coefficient of friction, and it is remarkable for its compatibility with the environmentally unharmful refrigerants, such as R134a (1,1,1,2-tetrafluoroethane), which are used today in refrigerating compressors without capillary tube obstructions.

  • Patent number: 6096826
    Abstract: A family of piperidone functionalized polymers based on polymers containing a plurality of hydroxyl groups. Piperidone or piperidone derivatives form a cyclic ketal linkage with hydroxyl groups contained on adjacent or alternating carbon atoms of the base polymer. Preferred compositions are piperidone functionalized poly(vinyl alcohol) having the following general formulae: ##STR1## wherein R.sub.1 through R.sub.6 are each independently hydrogen, methyl, or a C.sub.2 to C.sub.4 saturated or unsaturated alkyl groups, R.sub.7 is O.cndot. or OR.sub.8, wherein R.sub.8 is hydrogen or a C.sub.1 to C.sub.4 alkyl or C(.dbd.O)alkyl group; X.sup.- is a salt; x ranges from 50 to 99 mol %; y ranges from 0 to 30 mol %; and z ranges from 1 to 20 mol %. The compounds are useful in ink jet paper coating applications.
