Resum

The influence of the processing conditions on the relaxation in the glass transition range of a 50/50 mixtures of phenoxy and polyarilate has been investigated. Results obtained strongly suggest a crosslinking density increasing with the processing time. 1H NMR spectra cofirm the mechanism of crosslinking in the reaction between the hydroxyl group of the phenoxy and the carboxyl group of polyarilate
