“…Various NIPAM-free thermoresponsive polymers are known, for example, poly(N-vinylcaprolactam), 23,24 poly(methyl-2-propionamidoacrylate), 25 derivatives of maleic anhydride (MA) copolymers, 26,27 poly(organophosphazenes), 28 poly(N,N-diethylacrylamide-co-methacrylic acid), 29 methacrylamides with lactate side chains, 30 and poly(vinyl alcohol-co-vinyl acetates). 31 Special morphologies for pNIPAM-based thermoresponsive materials such as hydrogel nanoparticles, 32 poly(l-lactic acid) microcapsules as a pNIPAM gel container, 33,34 shell-crosslinked vesicles, 35 and an interpenetrating network with gelatin 36 were studied.…”

The controlled thermal release of aqueous solvent mixtures from polymeric gel particles was investigated. A new type of a polymeric gel consisting of a maleic anhydride/poly(ethylene glycol) condensation product as a crosslinking macromonomer and acrylamides was synthesized by solution or inverse emulsion polymerization for the investigation. Afterward a shell of crosslinked polystyrene was coated to stabilize this new kind of "microcontainer" for the application. This concept was shown as generally useful for various mixtures of organic solvents and water. The cloud point temperature of the polymer gel strongly depended on the following parameters: the type and content of organic cosolvent, the degree of polymerization and constituents of the polyester moiety, and the type and content of the comonomers

“…Recent results obtained by our group, 39,40 as well as the groups of Mattiasson 41 and Wu, 42,43 showed the universality of this approach to obtaining proteinlike copolymers capable of forming nanostructures with a core-shell morphology. It has been called conformationdependent copolymerization with simultaneous globule formation.…”

“…In this way, the two-layer globule will grow, retaining its core-shell (proteinlike) structure with a predominantly hydrophobic core and a hydrophilic outer envelope. Experimentally, this synthetic strategy was first realized by Lozinski et al 39 (see also ref. 40), who studied the redox-initiated free-radical copolymerization of thermosensitive N-vinylcaprolactam with hydrophilic N-vinylimidazole at different temperatures.…”

Although recent years have witnessed an impressive confluence of experiments and kinetic and statistical theories, presently there is no comprehensive understanding of the interrelation between chemical sequences in synthetic copolymers and the conditions of synthesis. For this problem, numerical simulations in conjunction with simple models provide a rather detailed answer. A survey is given of the simulation methods as applied to the design of nontrivial chemical sequences in copolymers obtained via heterogeneous radical polymerization. This review is focused on a recently developed approach, called conformation‐dependent sequence design, which takes into account a strong coupling between the conformation and primary structure of copolymers during their synthesis. We consider some applications of this technique, including the following problems and systems: (1) the design of sequences with long‐range correlations via solution radical copolymerization with simultaneous globule formation, (2) radical copolymerization near a chemically homogeneous surface leading to a copolymer with a gradient primary structure, and (3) template copolymerization near chemically patterned surfaces. © 2004 Wiley Periodicals, Inc.

“…There is a large demand for so-called intelligent smart materials: self-recovery, self-adjustment or control, selfdiagnosis, stand-by capability for detecting nonlinear onset, ability to be externally tuned, etc. [70]. Recombinant DNA technology can be utilized to produce polymers with specific properties and behavioral characteristics.…”

New trends in chemistry induced by genetic engineering and genomic information are analyzed. Genomic information and bioinformatics make the identification of all molecular participants of biological processes possible. The methods of identification of enzymeactive sites from sequence data were demonstrated. The problems of "chemical proteomics" were formulated and analyzed. New biocatalytic processes based on a new generation of enzymes, including CO 2 reduction and enzyme fuel cell construction, are demonstrated. It was shown that in many reactions the enzymes are substantially more efficient in comparison with classical chemical catalysts. The creation of recombinant proteins from unnatural amino acids is demonstrated, and organisms containing such proteins are described. The new trends of proteomics and bioanalytical chemistry in the postgenomic era are discussed.
