DIAMINE COMPOUND HAVING PHOSPHORYLCHOLINE GROUP, POLYMER THEREOF AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is a highly polymerizable diamine compound containing a phosphorylcholine group. Also disclosed is a high molecular weight polymer which uses the phosphorylcholine group-containing highly polymerizable diamine compound as one of the starting raw materials and is improved in mechanical strength, water resistance and heat resistance, while maintaining excellent biocompatibility and workability as an MPC polymer. Further disclosed is a method for producing such a high molecular weight polymer. Specifically disclosed is a specific diamine compound represented by the formula (I) below and containing a phosphorylcholine group. Also specifically disclosed is a polymer represented by the formula (II) below and having a number average molecular weight of not less than 5,000, while containing at least 1% by mole of a specific structural unit having a phosphorylcholine group. Further specifically disclosed is a method for producing such a polymer by using the diamine compound as one of the raw materials.
