Sequence regulation in living anionic terpolymerization of styrene and two categories of 1,1-diphenylethylene (DPE) derivatives

Abstract: It is an effective method to synthesize the functionalized sequence-controlled polymers by utilizing 1,1-diphenylethylene (DPE) derivatives in living anionic polymerization. Considering the capacity of sequence information and the diversify of...

“…Alternating copolymers display significant differences in both monomer sequence distributions and properties compared with the other traditional structures (such as random, gradient, and block copolymers). , DPE derivatives have been successfully applied in the synthesis of alternating copolymers by AP. The pivotal findings can be summarized as follows: (1) for DPE derivatives with high reactivity ( r D = 0, r M < < 1), it is easy to achieve strictly alternating copolymerization by controlling the monomer feed ratios; (2) for DPE derivatives with moderate reactivity ( r D = 0, r M ≈ 1), alternating copolymerization with defect sequences in chains can be achieved (an appropriate monomer feed ratio is necessary); (3) for DPE derivatives with low reactivity ( r D = 0, r M > > 1), it is impossible to achieve alternating copolymerization . The abovementioned kinetic principles are true for almost all anionic copolymerization reactions with DPE derivatives.…”

“…Although theoretically mBCPs with any architecture can be obtained via modern synthetic tools such as sequential living/controlled polymerizations, their synthesis is still difficult and time-consuming. Thus, obtaining different types of mBCPs for just the aesthetic purpose is not practical.…”

“…4,5 However, for the former, the species of functional monomer that can be used for polymerization are limited due to the side reaction problems induced by polar functional groups. 6,7 For the latter, it is necessary to execute modification reactions in solution and even introduce catalysts to obtain target functionalization. 8 This technique therefore results in unnecessary afterprocessing steps, unfriendly environmental effects, and unmatched processes with the manufactured rubber.…”

“…Increasingly, the high-performance capabilities that are required in rubber compounds can be effectively achieved through functionalization. Some conventional polymer functionalization techniques include the introduction of directly functional monomers into polymer chains via polymerization , or functional group grafting via postmodifications. , However, for the former, the species of functional monomer that can be used for polymerization are limited due to the side reaction problems induced by polar functional groups. , For the latter, it is necessary to execute modification reactions in solution and even introduce catalysts to obtain target functionalization .
