The search for new and unusual resins is most often carried out in the laboratories of large industrial producers. The practical aspects of the problem receive much attention while the theoretical studies must be neglected. Resins derived from cyclopentadiene are not as present produced commercially, but they do have many potentially desirable properties. Therefore, such resins may be produced on a large scale in the near future. At such a time a knowledge of the structure of the cyclopentadiene polymers would aid in the formulation of various modifications of the resins. For this reason a study of the structures of two types of cyclopentadiene polymers was undertaken. The results of this study should be useful. Formulas are derived on the basis of experimental evidence which show the probable structure of the cyclopentadiene polymers. These results should help to clear up conflicting statements in the literature which concern the structure and the size of the cyclopentadiene polymers.
