Qualitative Gas Chromatographic Analysis of Vinyl Ester Resins After chemical Degration
INTRODUCTION
Acid fusion reaction has been demonstrated by Williams and Siggia, [1] to cleave a series of vinyl polymers, including polyvinyl acetate, polyvinyl propionate, polyethylene-vinyl acetate, poly n-vinyl pyrrolidone-vinyl acetate, and polyvinyl alcohol. The acidic hydrolysis was conducted at an elevated temperature using concentrated reactants, either phosphoric acid, phosphorous acid, benzene phosphoric acid, sodium bisulfate monohydrate, or p-toluene sulfonic acid monohydrate. The corresponding fragments were then estimated by gas chromatography. these ...
