“…It follows that a completely neutralized PEC (a stoichiometric PEC) coexists with an excess of completely free polyelectrolytes in solution. This behaviour represents the all-or-none type complexation, and is depicted in eqn (19). This …”

“…112 One of the ways of enhancing the antithrombogenic properties of polymers involves the formation on their surfaces of polyelectrolyte complexes (PEC). 113,114 PEC are formed on the surfaces of polymers as a result of the interaction of the radiation-grafted poly(acrylic acid) with polyamines. The appearance of PEC gives rise to the formation of a microheterogeneous structure with alternation of hydrophilic and hydrophobic sections.…”

Compatibility of PVC with liquid alkyltin alkylthioglycolate stabilizers was studied by thermal methods, including isothermal calorimetry of mixing, DSC, DMA, and dielectric relaxation. The enthalpy of mixing of PVC with the series of alkyltin alkyl thioglycolates was measured over the entire concentration range at ambient conditions. It was found that all tested compounds are compatible with PVC in a broad concentration range and form homogeneous mixtures. The results are discussed in terms of the superposition of glassy state and molecular interaction contributions to the enthalpy of mixing of the glassy polymer with liquid additives. The influence of organotin stabilizers on the glassy structure of PVC films was studied by means of DSC and the dielectric relaxation spectrum. The enhancement of the glassy structure of PVC by alkyltin alkyl thioglycolates is interpreted as the result of strong multi‐site molecular complexes between organotin molecules and PVC chains, which act as additional clips in the entanglement network of polymer chains.
