摘要：
An ABA triblock copolymer with a mechanochemically active gem-dichlorocyclopropane rich polyester block is synthesized via chain extension with polymethylacrylate under SET-LRP conditions. The platform allows for the efficient mechanochemical ring opening of the gDCC groups to 2,3-dichloroalkenes, a promising approach to the synthesis of high mechanophore content polymers with enhanced stability.
