Blocks Can initiate anionic polymerization (in the presence of aluminum isopropoxide) and NMP through the alcohol and nitroxide functions An alkoxyamine with an appropriate functional group can be used to terminate a non NMP polymerization to yield a polymer with an alkoxyamine end group An existing polymer with an appropriate end group can be reacted with an alkoxyamine Star polymers are produced by using a core molecule that contains three or more alkoxyamine functions 9

Some final moments 11 The initiators need to be synthesized. K is generally larger for ATRP and easily adjusted by changing the initiator, transition metal, and ligands steady-state concentration of radicals is achieved by the balance between activation and deactivation

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
