Insoluble polyelectrolyte complex may be formed when dissolved acidic and basic polyelectrolyte polymers are brought into intimate contact (131). Complex formation is generally agreed to be driven by the increase in entropy associated with the loss of small counterions into the bulk of the solution (132). Polyelectrolyte complex from concentrated solutions of strongly acidic and basic homopolymers has been shown to form sufficiently rapidly to produce a 20-30 nm thick membrane at the solution interface, as was found through reaction of dissolved poly(vinylbenzyl trimethylammonium chloride) with sodium poly (styrene sulfonate) (132). 

The applications reported for polymer-supported, soluble oxidation catalysts are the use of poly(vinylbenzyl)trimethylammonium chloride for the autooxidation of 2,6-di-tert-butylphenol [8], of copper polyaniline nanocomposites for the Wacker oxidation reaction [9], of cationic polymers containing cobalt(II) phthalocyanate for the autooxidation of 2-mercaptoethanol [10] and oxidation of olefins [11], of polymer-bound phthalocyanines for oxidative decomposition of polychlorophenols [12], and of a norbornene-based polymer with polymer-fixed manganese(IV) complexes for the catalytic oxidation of alkanes [13], Noncatalytic processes can also be found, such as the use of soluble polystyrene-based sulfoxide reagents for Swern oxidation [14], The reactions listed above will be described in more detail in the following paragraphs. 

Another example of multicompartment micellar IPECs is the macromolec-ular co-assembly of the triblock terpolymer poly(Af,Af-dimethylacrylamide)- /ocfc-poly(A-acryloylalanine)-fetocA -poly(iV-isopropylacrylamide) or the diblock terpolymer poly(A,A-dimethylacrylamide)-fe/(9cA -poly(Ai-isopropylacrylamide)-stat-(A-acryloylvaline), interacting in aqueous media with poly(ar-vinylbenzyl) trimethylammonium chloride (PVBTAC) [76, 77], The authors demonstrated that interpolyelectrolyte complexation of such assemblies formed with PVBTAC within specific pH and temperature ranges makes them stable with respect to the disassembly induced by cooling below critical micellization temperatures. 

Double hydrophilic block copolymers, RB-3 and RB-4 have been prepared directly in aqueous media by using a dithioester-capped poly(4-styrene sulfate) or a dithioester-capped poly[(p-vinylbenzyl) trimethylammonium chloride] as the macrochain transfer agent in the successive RAFT polymerization of the second monomer [47]. The block copolymer, RB-5 was prepared using seeded emulsion polymerization via the RAFT mechanism. First, seeded particles consisting of PBA dormant chains were obtained by using active xanthate agent, [l-(0-ethylxanthyl)-ethyl]benzene, under bath and starved-feed...
