Abstract: The present invention relates to a method for removing bile acids from a patient and certain polymers of use in the method. The method comprises the step of administering to the patient a therapeutically effective amount of a polymer composition which includes a a poly(diallylamine) polymer which is substituted with hydrophobic groups. The hydrophobic groups can be a substituted or unsubstituted, straight chain or branched C3-C24-alkyl group, an aralkyl group or an aryl group.

Abstract: A method for removing bile salts from a patient that includes administering to the patient a therapeutically effective amount of a non-absorbable polydiallylamine polymers.

Abstract: A holographic recording medium comprises an acid generator capable of producing an acid upon exposure to actinic radiation; a binder; and at least one monomer or oligomer capable of undergoing cationic polymerization initiated by the acid produced from the acid generator. This recording medium is not subject to the disadvantages (for example, oxygen sensitivity) associated with radical-polymerized prior art holographic recording media.

Abstract: Disclosed are reactive anionic initiators of the general formula [ArCHR.sub.1 R.sub.2 N(R.sub.3 R.sub.4 R.sub.5 R.sub.6 ] wherein Ar=phenyl, substituted phenyl, or a heterocyclic compound, R.sub.1 =R.sub.2 =H, ester, cyano, alkyl, aryl, 1,3-oxazoline, N,N-dimethyl amide and other similar alpha activating groups, or combination of them, or one of R.sub.1 or R.sub.2 together with Ar, where Ar is a phenyl or substituted phenyl, is a nitrogen atom containing heterocyclic compound and the other being a nitrile group, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 may be same or different and represent substituted alkyl, cycloalkyl, arylalkyl or aryl or to of the R.sub.3, R.sub.4, R.sub.5 and R.sub.6 together with nitrogen atom form a heterocycle with the condition that the sum of all carbon atoms of all R.sub.3, R.sub.4, R.sub.5 and R.sub.6 is from 12 to 50 and no more than one of the R.sub.3, R.sub.4, R.sub.5 and R.sub.6 is an aryl derivative.
