(611f) Versatile Strategies to Tailor the Glass Transition Temperatures of Bottlebrush Polymers

This talk presents a strategy for tailoring the glass transition temperatures of bottlebrush polymers by manipulating various parameters, such as side chain length, backbone length, molecular weight composition, and topology. The study explores the impact of these parameters on the glass transition behavior of bottlebrush polymers and demonstrates a wide range of T_g values can be accessed through side chain engineering. The precision bottlebrush polymers (PBPs) used in the study yield precise T_g values, some of which can only be achieved through blending at the cost of T_g broadening. Additionally, multiblock PBPs offer the ability to target arbitrary T_g values while maintaining a sharp glass transition, combining the advantages of both approaches. Overall, the findings highlight the versatility of side chain engineering strategies in controlling the glass transition behavior of bottlebrush polymers.
