“…In our laboratory, an attempt has been made to prepare HAPAM via inverse miniemulsion polymerization using cationic hydrophobic monomer. In order to obtain HAPAM with higher thickening ability, we introduce template polymerization method [26][27][28] to the inverse miniemulsion system. In the presence of template, the oppositely charged monomer can form a longer hydrophobic block along the polymer chains.…”

Abstract. Cationic, hydrophobically associating polyacrylamide (PDA) was synthesized via the inverse miniemulsion polymerization in the presence of template. Dimethyloctane(2-acrylamidopropyl)ammoniumbromide (DOAB) was synthesized via quaternization reaction and used as the hydrophobic monomer. Polyacrylic acid (PAA) was used as template for the oppositely charged DOAB. The distribution of DOAB in the inverse miniemulsion and the solution viscosity behaviors of PDA were investigated. The results showed that the complexes of DOAB and PAA were located not only at the interface of the inverse miniemulsion droplets and oil phase but also in the interior of inverse miniemulsion droplets. PDA prepared with template exhibited remarkable enhancement of solution viscosity (thickening ability). And the optimal thickening ability was obtained when the aqueous phase pH was 6.5 and the ratio of DOAB to PAA was 1. The thickening ability of PDA was improved with increasing DOAB content. PDA prepared with template showed stronger association ability than that prepared without template for its longer hydrophobic block structure, which was further supported by the plots of fluorescence spectra.

“…For example, studies have been made on the polymerization of sodium acrylate, methacrylate and vinyl sulfonate onto synthetic templates, such as polyallylamine and poly(vinyl alcohol), where the role of interactions between carboxylic, hydroxylic and amine groups is very important, the same groups involved when polymerizing onto protein-like templates [10][11][12].…”

Past and recent attempts to introduce in synthetic polymers molecular information from natural substances through simple blending, template polymerization and molecular imprinting are reviewed. The most promising approaches that can open the way to the realisation of new materials with improved biocompatibility, antibody- or enzyme-like performances are analysed more deeply. The realisation of bioartificial blends from natural and synthetic polymers, molecularly imprinted nanospheres or membranes that can act as recognition element in (bio)sensing devices, as synthetic enzymes or as key constituents of body fluids purification tools is presented in order to make the reader aware of the fascinating possibilities that these techniques make available to the biomedical science and engineering in the close future. The last part of the paper describes recent attempts to insert recognition elements for large molecules as proteins, DNA segments, viruses or whole cells in synthetic polymer systems, in order to develop new systems in the treatments of diseases and for tissue-engineering applications.
