Abstract

This invention provides a kind of polycarbodiimide and its process. The process is started by hydrophilic grafting reaction, so that one end of diisocyanate is linked to hydrophile group. With phosphorus as catalyst and under high temperature, isocyanate having hydrophilic group undergoes elimination reaction to obtain polycarbodiimide. Subsequently, hydrophilic group is employed to block the end. The resulting polycarbodiimide has hydrophilic groups at both ends, and different from aqueous polycarbodiimide, possesses superior hydrophilic characteristic, while retaining the hardenability and stability of conventional polycarbodiimide.
