Polybase ionenes

The system with very strong interaction between monomer and template was studied by Blumstein at Polybase ionenes were used as templates. A set of ionenes such as...

On the other hand, when integral-type polycations (having cationic charges on the backbone chain) instead of pendant-type polycations, are used as strong polybases, different phenomena are observed. Tsuchida et al.m) discussed the interactions between NaSS and a series of integral-type polycations, called ionenes ... 

A large number of macromolecules complementary to PMAA, namely polyvinylpyrrolidone, polyvinylpyridine, polyacrylamide, poly(vinyl alcohol), poly(ethylene oxide), oligoethylenimine, poly(sodium styrene sulfonate), polycations of the integral type ionen (2X) were used as P2 and P3. The pH of the media strongly influences the studied reactions of complex formation. For example, in PVPy + PVP + PMAA or OEI + PEO + PMAA systems in the add region, where weak polybases are completely protonized and PMAA does practically not dissodate, complexes with hydrogen bonds (PMAA-PVP or PMAA-PEO) are formed. In neutral medium weak polybases are partially ionizated and polyelectrolyte complexes (PMAA-PVPy, PMAA-OEI) are generated. In the alkaline medium formation of complexes has not been observed. 

Tsuchida showed that in the case of PECs formed between weak polyacids and polybases, the hydrophobicity can influence the formation of PEC. The PEC formed between PMAA and 10,10-ionene was more than the PEC formed between polyfacrylic acid) (PAA) and 10,10-ionene as the PMAA is more hydrophobic than PAA.
