“…In our previous papers we have reported some information on the binding of mono-and divalent metal ions to PPP obtained from the conductivity data [9,10]. This report deals with spectral studies of the interaction between monovalent ions and a polyalkylene phosphate ion in PPP samples of a different degree of polymerization.…”

A poly(1,3-propylene phosphate), (PPP), which can be considered as a synthetic analogue of naturally occurring teichoic acids, has been studied with infrared spectroscopy. Infrared spectra of PPP in acidic and alkali metal forms have been analyzed in detail and the conclusions concerning intermolecular interactions between phosphate diester groups and the monovalent cation binding to PPP of a different degree of polymerization (n) have been drawn out. It has been shown that in anhydrous PPP, acidic groups are extensively hydrogen bonded. The process of association of phosphate diester groups is rather complex, especially in the samples of lower n. The role of H-bonds in some solution properties of high-molecular PPP samples has been discussed.

This article provides the up‐to‐date and comprehensive review (over 700 citations) of all the important subjects of the ring‐opening polymerization (ROP) methods of polymers syntheses. This is the method of synthesis of several important classes of polymers that cannot be prepared in a different way (e.g., polyethers). It also complements known methods of polycondensation and ROP often is the method of choice. ROP is particularly important in syntheses of the biodegradable polymers‐polylactide and poly(ε‐caprolactone), discussed in details. Applications of these polymers, as well as polysiloxanes in biomedical applications are irreplaceable in the modern medicine. Either as bulk polymers or as nano‐ and microspheres, described In this article separately. There are sections in the present version that were not presented in the previous editions. This is description of polyoxazolines, polymers with phosphorus atoms in the chains, as well as mentioned above polysiloxanes an microspheres. We introduced also section describing novel analytical methods, particularly useful in studies of polymers with various architectures (star shape, multibranched etc.). Besides the synthetic aspects of ROP, this article describes thermodynamics and kinetic features of the living/controlled polymerizations, particularly by activated monomer mechanism and importance of dormant polymers in precision syntheses of desired structures.

The problem of competitive metal ion binding to poly(alkylene phosphate)s, considered as synthetic models of natural teichoic acids, was analysed theoretically applying the Poisson‐Boltzmann (PB) equation to a cylindrical cell model. There were calculated the radial distribution functions as well as the degree of ion binding of mono‐and divalent metal ions to polyphosphate ions in solutions of different concentrations ranging from 10−5 M to 10−2 M and containing different amounts of M⊕ and M2+ counterions. For comparison, analogous calculations were performed also for poly(styrenesulfonate)s. The results indicate the preferential binding of divalent metal ions to polyphosphate ions over monovalent ones. The selectivity for M2+ ions is concentration dependent and increases with decreasing the polymer solution concentration. It results from PB calculations, that condensation of divalent metal ions at the surface of polyion chains seems to be responsible for preferential binding of biologically important metal ions, for example magnesium, to natural teichoic acids and their synthetic analogues.
