This document discusses two methods for synthesizing bottlebrush polymers: grafting-from and transfer-to. Bottlebrush polymers have rigid, nanoscopic structures that give them unique mechanical and rheological properties. The transfer-to approach combines grafting-from and grafting-to by allowing polymeric radicals to detach from the backbone and reattach through a chain transfer reaction, allowing for lower dispersities and higher conversions than traditional grafting-from. The document aims to compare the transfer-to and grafting-from methods using size exclusion chromatography and nuclear magnetic resonance spectroscopy to highlight the differences between the two techniques.
