✦ Synopsis

The thermodynamics of proton dissociation of the hydrolysed 1 : 1 copolymer of maleic anhydride with cyclopentene in aqueous solution has been investigated. Potentiometric, microcalorimetric and dilatometric measurements on the copolymer solutions indicate that the two acidic functions are quite strong and not very different. Relatively poor solvation of vicinal carboxyl groups could account for the behaviour of the copolymer" it could stem from steric hindrances imposed by the cyclopentene residues.
