The gamma irradiation of mixtures of carbon dioxide with ethylene yielded long-chain carboxylic acids. The G(-ethylene) values varied with reaction temperature from essentially zero at -78 degrees C to 175 at 100 degrees C. Under the same conditions, the substitution of free radical agents for radiation gave polyethylene.
二氧化碳与乙烯的混合物经伽马辐射后生成了长链羧酸。G(-乙烯)值随反应温度而变化,在-78°C时基本为零,在 100°C时则为 175。在相同条件下,用自由基试剂代替辐射可得到聚乙烯。
