作者:盧世琴

摘要：

聚2-甲基1,3-丁二烯爆米花聚合物之氧化生成物其具有揮發性之化合物中，定量測定水及二氧化碳，半定量測定甲醛，此三種生成物皆與所用氧量成直線關 係。每用一莫耳之氧生成0.098莫耳之水及0.038莫耳之二氧化碳及多於0.016莫耳之甲醛。總共有二十四種生成物，由於繼續氧化及相互作用而生 成。其主要者為水、二氧化碳、甲醛、甲酸及乙酸，無4.羰基戊醛(levulinaldehyde)發見。
本文提出一可能之反應機構討論。

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.
