Parkatzidis, Kostas; Rolland, Manon; Truong, Nghia P.; Anastasaki, Athina published the article 《Tailoring polymer dispersity by mixing ATRP initiators》. Keywords: polymethyl acrylate preparation ATRP initiator polymer dispersity kinetics.They researched the compound: Cupric bromide( cas:7789-45-9 ).Application In Synthesis of Cupric bromide. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:7789-45-9) here.
Herein we present a simple batch method to control polymer dispersity using a mixture of two ATRP initiators with different reactivities. A wide dispersity spectrum (D ∼ 1.1-1.7) is achieved by altering the ratio between the two ATRP initiators while sustaining fairly monomodal mol. weight distributions. Depending on the targeted dispersity, a distinct kinetic profile was observed and, in contrast to previous ATRP approaches, near-quant. conversions were obtained even for the highest dispersities. High end-group fidelity was also maintained in all cases as exemplified by chain extensions. Significantly, this method can be applied to various ATRP protocols as well as to various monomer classes.
