Abstract : The kinetics of dehydration and decarboxylation as well as the glass transition temperature as a function of anhydride content were measured for poly(acrylic acid). It was found that the glass transition of PAA is of the order of 103C and increases with increasing anhydride content, reaching an extrapolated value of 140C for the pure linear anhydride. Anhydride formation is first order reaction, as is also decarboxylation, the latter being much slower than the former. Anhydride formation occurs primarily by an intramolecular process. (Author)
