Abstract:
Block polymers are formed by ring opening polymerization (ROP) of a cyclic carbonate monomer using a polymeric initiator for the ROP that comprises repeating functionalized ethylene units. The block polymers are free of, or substantially free of, any polymer having a chemical structure that does not comprise the polymer backbone of the polymeric initiator. The block polymers are capable of directed self-assembly.
