functionality pales in comparison to natural biopolymers–strategies are limited for building the intricate network of noncovalent interactions necessary to elicit complex, protein-like functions. Using a bioinspired di(phenylalanine) acrylamide (FF) monomer, we explored the impact of various noncovalent interactions in generating ordered assembled structures. Amphiphiliccopolymers were synthesized that

pentafluorophenyl acrylate (PFPA) and ABdiblock copolymers of N,N‐dimethylacrylamide (DMA) and poly(ethylene glycol) methyl ether acrylate (PEGA) with PFPA were prepared by reversibleaddition–fragmentationchaintransfer (RAFT) radical polymerization. Three PFPA homopolymers of different molecular weights were reacted with the commercially available amidine and guanidine species histamine (HIS) dihydrochloride and
通过可逆加成-断裂链转移(RAFT)自由基制备了定义明确的五氟苯基丙烯酸酯(PFPA)均聚物和N,N-二甲基丙烯酰胺(DMA)和聚(乙二醇)甲基醚丙烯酸酯(PEGA)与PFPA的AB二嵌段共聚物聚合。在S-甲基甲硫基磺酸盐的存在下,将三种不同分子量的PFPA均聚物与市售的am和胍类组胺(HIS)二盐酸盐和L-精氨酸甲酯(ARG)二盐酸盐反应,定量得到相应的am和胍基于丙烯酰胺均聚物。已知HIS和ARG均聚物都可逆地结合CO 2在前者的情况下,CO 2固定伴随着从疏水状态到亲水状态的转变。PFPA-DMA和PEGA-PFPA二嵌段共聚物的RAFT合成产生了具有各种摩尔组成的明确定义的材料。这些前体材料被转化为相应的HIS和ARG嵌段共聚物,其结构已通过1 H NMR光谱法确认。通过结合使用动态光散射和透射电子显微镜,我们证明了DMA-HIS和PEGA-HIS二嵌段共聚物能够在水性介质中使用CO

A process for producing polymer-functionalized filler particles and polymer-functionalized filler particles obtained by this process. The polymer-functionalized filler particles are used as additives for rubber mixtures. The polymers for functionalizing the filler particles are obtained in-situ starting from filler particles having a surface-bound RAFT agent. The binding of silyl-bearing RAFT agents and of Diels-Alder RAFT agents occurs via the R-group and the subsequent RAFT polymerization proceeds via a reactive site of the RAFT agent.
