Abstract

XI X natural rubber, the synthetic all-cis poly-1, Z-dimethylenecyclohexane was a highly crystalline solid, melting at 165'. To determine the reason for this striking difference, a series of related cyclic dienes with various substituents were synthesized. One cyclic diene of interest was 2, 3-dimethylenebicyclo [2.2. l] heptane (I). The polymer prepared from I should allow determination of the effect of the very rigid bicyclo ring system and the asymmetry ...
