虽然环氧乙烷、四氢呋喃、乙亚胺、β-丙内酯和己内酰胺等杂环化合物的离子开环聚合以及环戊烯和降冰片烯等环烯烃的Ziegler-Natta开环聚合是众所周知的，但自由基开环聚合相当少见。文献中报道的少数例子涉及环丙烷衍生物或高度应变的双环烯烃。例如，Takahashi[L]研究了乙烯基环丙烷的自由基聚合，并报道了环丙烷开环后得到的聚合物含有约80%的1，5-单元和约20%的未确定结构单元。
Although the ionic ring-opening polymerization of heterocyclic compounds, such as ethylene oxide, tetrahydrofuran, ethylen-imine, β-propiolactone, and caprolactam, as well as the Ziegler-Natta ring-opening of cyclic olefins, such as cyclopentene and norbornene, are well known, free radical ring-opening polymerizations are rather rare. The few examples that are reported in the literature involve cyclopropane derivatives or highly strained bi-cyclic olefins. For example, Takahashi [l] studied the free radical polymerization of vinylcyclopropane and reported that the cyclopropane ring opened to give a polymer containing about 80% 1,5-units and about 20% of undetermined structural units.
