The synthesis and morphology characterization (SEM, AFM) of a family of new (R)- and (S)-polycarbodiimides of different composition bearing active ethynyl groups was accomplished under the standard carbodiimide polymerization conditions (e.g. using BINOL Ti-catalyst). The alkyne functionalities in repeat units offer an opportunity for further post-modification thru CuAAC �click�-chemistry protocol leading to cross-linked and PEG-polymers suitable for drug delivery applications.
