The structural versatility of pseudopoly (amino acids) can be increased further by considering dipeptides as monomeric starting materials as well. In this case polymerizations can be designed that involve one of the amino acid side chains and the C terminus, one of the amino acid side chains and the N terminus, or both of the amino acid side chains as reactive groups. The use of dipeptides as monomers in the manner described above results in the formation of copolymers in which amide bonds and nonamide linkages strictly alternate (Fig. 3). It is noteworthy that these polymers have both an amino function and a carboxylic acid function as pendant chains. This feature should facilitate the attachment of drug molecules or crosslinkers,... 

A series of fluorene copolymers with amino-functionalized side chains 373 and 374 has been prepared by the same group (Chart 2.92). Upon quaternization, they gave copolymers 375 and 376, which were soluble in polar solvents (methanol, DMF, DMSO) [439]. Devices from the... 

The low thermal stability and the volatility of some of the low molecular weight stationary phases restricted their general use. Therefore, thermally stable and nonvolatile polymeric chiral stationary phases were developed by coupling the diamide phase, via the amino functionality, to a statistical copolymer of dimethylsiloxane and (2-carboxypropyl)methylsiloxane of appropriate viscosity131. The fluid polymeric phase, referred to as Chirasil-Val (Table 2), exhibits excellent properties for the enantiomer separation of a variety of compound classes over a broad temperature range141142.

Reynhout et al. [52] recently published a completely solid phase method for the synthesis of peptide-based triblock copolymers. Amine-functionalized polystyrene was first coupled to an aldehyde-modified resin to give a polystyrene functionalized secondary amine on the resin, which could then be coupled to the next amino acid (Fig. 11). Then the sequence Gly - Ala - Asn -Pro - Asn - Ala - Ala - Gly (GANPNAAG)—a known -hairpin folding peptide found in the CS protein of the Malaria parasite plasmodium falciparum— was synthesized, using standard Fmoc peptide chemistry. After removing the final Fmoc group from the peptide, a carboxylic acid-functionalized polystyrene was coupled to the terminal amine.

Various linear block copolymers of the AB, ABA and ABC type with enzymatically polymerized amylose blocks were reported. Ziegast and Pfannemuller converted the hydroxyl end groups of poly(ethylene oxide) into amino groups via tosylation and further reaction with 2-aminoalkylthiolate. To the resulting mono- and di-amino functionalized poly(ethylene oxide) maltooligosaccharide lactones were attached and subsequently elongated to amylose via enzymatic polymerization. Pfannemuller et al. performed a very detailed study on the solution properties of the synthesized A-B-A triblock...
