Three polymerizable surfactants (surfmers) bearing 2-acrylamido-2-methylpropanesulfonic acid (AMPS) as group in the counterion have been designed, synthesized, and their micelle-forming properties investigated different solvents. Solutions of dodecylammonium (DDA-AMPS), cetylammonium (CA-AMPS), cetyltrimethylammonium (CTA-AMPS) 2-acrylamido-2-methylpropanesulfonates were studied water, water–dioxane mixtures a whole range components ratios, xylene. The solutions by capillary rotational...
Abstract Conformations of two linear, charged dendronized polymers in aqueous solutions different ionic strengths have been studied by light scattering. Both a polyacrylic core. The repeating unit the first contains residue aspartic acid bound to carboxylic group core an amide as first‐generation dendron, whereas second polymer second‐generation dendrons constructed three molecules acid. dendritic adopt conformations depending on generation. Polymers with are flexible and their conformation...
Abstract Summary: A new principle for the design of dendritic macromolecules – ionic binding linear chain polyelectrolyte with oppositely charged focal ionogenic groups dendrons has been developed. The majority complexes (DICs) are prepared poly(styrenesulfonic acid) (PSS) as a polymeric core and L ‐aspartic acid different generations. Two series DICs were using PSS aspartic bearing terminal (located at external periphery) methoxycarbonyl hexyloxycarbonyl (C1‐ n C6‐ respectively where is...
Abstract Different approaches, including polycondensation, polymerization, polymer analog condensation, and ionic binding have been investigated for synthesis of amino acid‐based dendritic polymers. It was shown that a growth dendrons generation prevents obtaining products with high polymerization degree in polycondensation procedures. In condensation leads to considerable decrease reaction rate as well substitution degree. Degree depends on strength ionogenic groups dendrns generation.
Several series of liquid crystalline poly[aroyl-bis(oxyarylates)] with oligomethylene (n = 6 and 10) oligooxyethylene 2; 3; 4 6) spacers were synthesized. The structure their mesogenic groups was varied by replacement central or terminal units those reduced symmetry. polymers investigated methods, such as differential scanning calorimetry, polarizing optical microscopy in some selected cases X-ray diffraction methods using synchrotron radiation. An absence transesterification during...
Synthesis and self-organization studies of polyionic complexes linear–dendritic copolymers based on polyethylene glycols bearing aspartic dendrons with terminal amino carboxylic groups.
Linear polymers with dendrons of first and second generations based on L-aspargic acid are studied by the methods flow birefringence electric birefringence. Optical, dipole, dynamic, conformational properties macromolecules, as well contributions to their optical anisotropy due macroform microform effects, investigated. The found possess permanent dipole moments undergo reorientation in external hydrodynamic fields according large-scale rotation mechanism. A significant growth equilibrium...
Abstract Synthetic approaches which allow to insert rather long fragments with exactly definite sequence of several single structural units into polymer chains are considered and summarized. The procedure consists in preliminary formation such sequences a form bifunctional “complex monomer” (synthons) may undergo polycondensation other or complex monomer macromolecule alternation monomers. These synthetic were used for the synthesis LC multi‐block copolymers structure rigid block.
