Relationship between blood compatibility of polymer material and water structure in it

We had already reported poly(2-methoxyetylacrylate) (PMEA) shows good blood compatibility. To clarify this reason we focused on water structure in it and found that PMEA has unique cold-crystallizable water (defined as freezing bound water). The relationship between freezing bound water and blood compatibility was investigated in detail by using MEA copolymer and several poly(methacrylate)s, and it was concluded that this water would play an important roll in PMEA's exhibitting the compatibility.
