## Abstract **Summary:** The crystal structure of syndiotactic 3,4‐poly(2‐methyl‐1,3‐butadiene) has been determined by the joint use of molecular mechanics and X‐ray diffraction. Molecular mechanics calculations have been performed both on the isolated chain and on the crystal by the use of various
## Abstract The crystal structure of isotactic __cis__‐1,4‐poly(1,3‐hexadiene) has been determined through a combination of X‐ray diffraction analysis and molecular mechanics. Two reasonable values for unit cell parameters were obtained from the fiber diffraction pattern of a well‐oriented sample.
