    摘要: 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.

    摘要: An electro-optic display comprises first and second substrates, and an adhesive layer and a layer of electro-optic material disposed between these substrates, the adhesive layer comprising a mixture of a polymeric adhesive material and an additive selected from a salt, a polyelectrolyte, a polymer electrolyte, a solid electrolyte, a conductive metal powder, a ferrofluid, a non-reactive solvent, a conductive organic compound, and combinations thereof. The additive enables the volume resistivity of the adhesive layer to be controlled. Also, in an encapsulated electrophoretic medium comprising capsules in a polymeric binder, the volume resistivity of the binder can be controlled in a similar manner.
