Oxidation of Polyisoprene Popcorn Polymer

Author: Shih-Chen LU

Abstract：

The volatile products resulting from polyisoprene popcorn polymer oxida-tion were analyzed quantitatively for carbon dioxide and water, and semiquant-itatively for formaldehyde. The production of these three products was a linear function of the amount of oxygen consumed in the reaction. For every mole of oxygen reacted, 0.098 mole of water, 0.038 mole of carbon dioxide, and>0.0!6 mole of formaldehyde were formed. Twenty-four products were detected after extensive oxidation; the major ones being water, carbon dioxide, formaldehyde, formic acid, and acetic acid. No levulinaldehyde was identified in the products.
A tentative oxidation mechanism is discussed.
