Polyethylene Glycol Containing Rompolymers For The Modification Of Neuro-Protective Hemoglobin, Andrea L. Mccollum

Honors College Theses

Polyethylene glycol (PEG) has shown the ability to improve compatibility when used in combination with cell-free hemoglobin in the treatment of traumatic brain injuries. It has been demonstrated that the covalently bonded PEG increases the hydrodynamic radius of the hemoglobin and hence generates a physical barrier while slowing down the oxygen delivery of the strongly oxidative hemoglobin. In this context, I have been working on the development of synthetic pathways to incorporate PEG into monomers and polymers through both direct modification of (7-oxa)norbornene derivatives and post polymerization modification. Starting from the (7-oxa)norbornene anhydride derivatives, we have developed pathways to cationic …
