This research, a new diblock copolymer, poly(glutamic acid)-bpoly(benzyl glutamate-r-octadecyl glutamate) was synthesized and characterized. A precursor, poly(tert-butyl glutamate)-b-poly(benzyl glutamate-r-octadecyl glutamate) with tert-butyl as an acid-labile protecting group for the carboxylic acid group was first synthesized, followed by the removal of the tert-butyl groups to yield the desired amphiphilic diblock copolymer. |
