Synthesis and Characterization of Linear, Homopolyester, Benzoyl-Protected Bis-MPA

Autor: Sergei Nazarenko, Christopher B. Keller, Scott M. Grayson, Beibei Chen, Oluwapelumi O. Kareem, Samantha P. Daymon

Publikováno v: Macromolecules. 53:6608-6618

Because of the growing interest in bis-MPA dendrimers and hyperbranched polymers, a linear, polyester equivalent is of great importance in understanding how this commercially viable family of branc...

Oil spill accidents are a major concern for aquatic organisms. In recent history, the Deepwater Horizon blowout spilled 500 million liters of crude oil into the Gulf of Mexico. Corexit 9500A was used to disperse the oil since it was the method approv
