Preparation and in vitro blood-compatibility of amphiphilic coupling-polymer surface coating on polyurethane guiding catheters for biomedical applications

摘要

Three types of stearyl poly (ethylene oxide)(SPEO) with different Mn, 2300, 6000 and 12000, were synthesized by an anion polymerization from the ethylene oxide (DO) monomer with the catalyst, sodium salt of stearyl alcohol.
