摘要: Abstract The aim of this work was to study the cross-linkage xerogels made Carbopol ® different molecular weight (polymers deriving from polyacrylic acid), and influence exerted by percentages β-cyclodextrin upon percentage. Xerogels were obtained high-pressure compression cross-linking studied measuring loss formulations over a temperature range 70 190 °C. Kinetics anhydride formation found follow second-order mechanism with an activation energy approximately 25 kcal mol −1 .
