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： Aqueous polyurethane dispersions comprising polyurethane polymer and methods for making and using same are disclosed herein. In one aspect of the present invention, aqueous polyurethane dispersions, comprising a polyurethane polymer having a weight average molecular weight ranging from 20,000 to 80,000, are prepared by controlling the weight average molecular weight of the polymer by reacting the isocyanate terminated prepolymer with at least one chain terminating agent; and/or maintaining a N/COOH molar ratio of amine in the neutralizing agent to acid functional group in the isocyanate reactive compound to from about 0.5:1 to about 1:1.

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.
