用有机铝化合物、乙酰氯-金属卤化物和乙酸酐-高氯酸作为引发剂研究了1,3-二氧戊环的聚合反应。使用这些引发剂可以轻松获得聚 1,3-二氧戊环，它是一种白色结晶固体，熔点为 50–55°C。 C2原子上有取代基的1,3-二氧戊环不能用上述引发剂聚合，而C4原子上有取代基的1,3-二氧戊环只能聚合成粘性物质，尽管聚合速率比未取代的1,3-二氧戊环慢。讨论了阳离子聚合中1,3-二氧戊环断键的位置。
Polymerization of 1,3-dioxolane was examined with organo-aluminum compounds, acetyl chloride-metal halides, and acetic anhydride-perchloric acid as initiators. Poly-1,3-dioxolane obtained easily with these initiators was a white crystalline solid with a melting point of 50–55°C. 1,3-Dioxolanes with a substituent at C2-atom could not be polymerized with the initiators described above, while those having a substituent at C4-atom only polymerized to viscous materials, even though the rate of polymerization was slower than that of unsubstituted 1,3-dioxolane. A discussion about the position of bond scission of the 1,3-dioxolane ring in cationic polymerization is presented.
