Polymerization peroxycarboxylic acids

Formation of polymeric peroxycarboxylic acids of variously grafted celluloses, such as 228 and 229, where the thick line represents the main cellulose strand, and assessment of their thermal stability by following their decomposition at various temperatures is based on iodometric determination of the peracids . 

Peroxycarboxylic acid esters are utilized as initiators for radical polymerization and are interesting intermediates for the decarboxylation of carboxylic acids. They are generally prepared by the acylation of hydro peroxides with acid chlorides, acid anhydrides, or imidazolides in the presence of a base. Condensation of carboxylic acids (20) with /-butyl-hydroperoxide (21) has been smoothly achieved by the use of diethyl phophorocyanidate and NEt3 under mild conditions giving f-butyl peroxycarboxylates (22) in good yield.9...
