The Discovery of Polyethylene and Its Effect on the Evolution of Polymer Science,he creation of the novel materials necessary for these new technologies to become possible. What is staggering in retrospect, was the rate at which these new materials were created and brought into use.

History of Helical Structures in Vinyl Polymers,rsional angles defining this rotational isomeric state are repeated regularly along the polymer chain.
