✦ Synopsis

Abstract~omplex formation for poly(methacrylic acid) and poly(acrylic acid) with 2-acetoxybenzoate derivatives of poly(ethylene glycol)s was studied in dilute aqueous solution by potentiometric titration and viscometry. The hydrophobic 2-acetoxybenzoate end-groups were found to stabilize the polycomplexes. The polycomplexes of poly(methacrylic acid) are stable at pH below 6. Introducing biologically active hydrophobic compounds in poly(ethylene glycol)s offers possibilities of developing new drugs on the basis of polycomplexes.
