ABSTRACT:
Highly polymerizable diamine compounds having a phosphorylcholine group are disclosed. High-molecular weight polymers are obtained from the highly polymerizable diamine compound having a phosphorylcholine group as a monomer, and the polymers have improved mechanical strength, water resistance and heat resistance while maintaining excellent biocompatibility and processability of MPC polymers. Processes for producing the polymers are disclosed. The diamine compounds having a phosphorylcholine group are represented by Formula (I). The polymers contain at least 1 mol % of a specific structural unit with a phosphorylcholine group represented by Formula (II) and have a number average molecular weight of not less than 5,000. In the processes, the diamine compound is used as a monomer.
