In addition to their classical use as ion exchangers, insoluble polymers have been widely used in recent years as supports for solid-phase~ nthesis l), chromatography 2) and as carriers of organic reagents 3), catalysts 4), enzymes s), and pharmacologically active compounds 6). The advantages of this approach are the simulation of high dilution or pseudodilution conditions, the fish-hook and concentration principle, the facilitation of selective intrapolymeric reactions, stabilization of reactive species and the elimination of volatile malodorous reagents 7). The easy separation of the by-products of the reaction is an important advantage of the use of insoluble polymeric reagents. The question of the achievement of the site isolation and the chemical and kinetical non-equivalence of the reaction sites can be visualized as serious disadvantages of the reactions in such polymeric matrices s). In this context, the use of linear soluble polymers in the place of the cross-linked insoluble resins would be advantageous in many respects. The separation of the polymers may raise an operational problem in some cases; however, in most cases, the soluble polymer permits separation by selective precipitation or by membrane illtration. These considerations have awakened much interest nowadays in the application of linear soluble polymers as supports for sequential type organic syntheses, as carriers of organic reagents, enzymes, catalysts, as complexing agents and as polymeric drugs. A critical survey of the literature concerning the use of soluble polymers for these purposes is attempted here.
