Brandon R. Clarke*, Hyemin Kim*, Mark Ilton, James J. Watkins*, Alfred J. Crosby*, and Gregory N. Tew* have published a paper in Macromolecules entitled The Impact of Polymerization Chemistry on the Mechanical Properties of Poly(dimethylsiloxane) Bottlebrush Elastomers.

A new parameter coined the 'Structural Efficiency Ratio' is developed to evaluate the effectiveness of different chemistries at forming stress-supporting strands. This new parameter informs how manipulation of polymerization chemistry affects the mechanical properties of structurally similar bottlebrush elastomers.
