## Abstract The crystal structure of isotactic __cis__β1,4βpoly(1,3βhexadiene) has been determined through a combination of Xβray diffraction analysis and molecular mechanics. Two reasonable values for unit cell parameters were obtained from the fiber diffraction pattern of a wellβoriented sample.
## Abstract **Summary:** The crystal structure of syndiotactic 3,4βpoly(2βmethylβ1,3βbutadiene) has been determined by the joint use of molecular mechanics and Xβray diffraction. Molecular mechanics calculations have been performed both on the isolated chain and on the crystal by the use of various
