Abstract
Novel thermoplastic polyelectrolyte complexes are disclosed which are the reaction products of (a) a polyanion and (b) a polycation wherein one of the polyanion and polycation contains repeating units derived from a soft monomer. By the selection of said soft monomers and of the cation group present in the polycation, moldable, extrudable polyelectrolyte complexes are obtained.
Claims15
A thermoplastic polyelectrolyte complex comprising (a) a water-soluble polyanion which is a polymer having a plurality of anionic groups which polyanion is ionically crosslinked with (b) a water-soluble polycation which polycation is a polymer containing a plurality of pendant cationic moieties wherein at least one of the polyanion or polycation contains repeating soft mers, and wherein the proportion of said soft mers contained in said polyanion and polycation and the cationic moieties present in said polycation are chosen such that said polyelectrolyte complex is thermoplastic.
