Abstract
In one aspect, oligomeric and polymeric species are described herein exhibiting new architectures and associated properties. In some embodiments, such species are synthesized by oligomerization or polymerization of diene monomer via cycloaddition in the presence of a transition metal complex. Oligomers described herein, for example, comprise cyclobutane units in the oligomer backbone. Similarly, a polymers described herein comprise cyclobutane units in the polymer backbone.
