Abstract
Polymerization of allyl methacrylate (AMA) with wool fabrics using different initiators, namely, potassium persulphate, Fe^2+^H~2~O~2~, benzoyl peroxide, ceric ammonium nitrate, and vanadium pentanitrate, was investigated. The percent of polymer add‐on depends upon the type and concentration of the initiator. Addition of metallic salts such as Fe^3+^ to the polymerization system enhances polymerization significantly when benzoyl peroxide and potassium persulphate are used independently as initiator. The opposite holds true for ceric ammonium nitrate and vanadium pentanitrate. With Fe^2+^H~2~O~2~, on the other hand, the enhancement is marginal. Also studied was the incorporation of Li^+^, Cu^++^, and Fe^3+^ at different concentrations in AMA—wool–benzoyl peroxide polymerization systems. Determination of the polymer add‐on on the basis of double bond analysis revealed that the remained double bond is governed by the magnitude of the polymer add‐on as well as by the type of initiator.
