Abstract
A zwitterionic/amphiphilic pentablock copolymer was prepared using atom transfer radical polymerization (ATRP). The pentablock copolymer is prepared for the atom transfer radical polymerization of a PDMS-PEO-Br macroinitiator and SBMA. The pentablock copolymer is incorporated into a polyurethane coating composition which is useful for antifouling and/or fouling release applications.
