PPP Polyelectrolytes via Amino Intermediates

Because of the findings reported above, the development of a new strategy was recently started which should make available PPPs which are soluble in water even at vanishing charge density. The key step of this new strategy is the attachment of oligoethylene oxide (OEO) side chains to the PPP backbone [27]. These substituents should allow  

avoidance of the apolar alkyl side chains and, moreover, 

efficient prevention of hydrophobic interactions of the apolar PPP main chains. 

A positive side-effect of the new strategy is a clearly simplified and accelerated polyelectrolyte synthesis the monomers are quickly available and the time-consuming ether cleavage is no longer necessary. Despite the fact that not all desired materials could yet be obtained, we nevertheless can recon-
