Kinetics of anhydride formation in xerogels of poly(acrylic acid).

Abstract

The aim of this work was to study the cross-linkage of xerogels made of Carbopol of different molecular weight (polymers deriving from polyacrylic acid), and the influence exerted by different percentages of beta-cyclodextrin upon the cross-linkage percentage. Xerogels were obtained by high-pressure compression and cross-linking was studied by measuring the… (More)
