| Popis: | In the oxidation of isotactic polypropylene, qualitative and quantitative studies were made of organic volatile products by gas chromatographic methods. Experimental results and further data have been compared. Most of the products formed during degradation are acetone, and other ketones and aldehydes. Propylene, acetic acid and 2.4-dimethyl furane have also been identified. The products are formed in an accelerating kinetic process. There was linear relationship between the volatile products measured and the amount of oxygen consumption: approximately 2% of the oxygen absorbed is built into low molecular weight organic carbonyl compounds. |
