A polycarbodiimide represented by the formula (I):wherein R1 is an alkylene group having 2 to 10 carbon atoms, R2 is a divalent aromatic group, R3 is a monovalent aromatic group, k is 0 or an integer of 1 to 30, m is an integer of 2 to 100, and n is 0 or an integer of 1 to 30, a process for preparing the same and uses of the polycarbodiimide. The polycarbodiimide is favorably used in the form of films such as adhesive films for die bonding and adhesive films for underfilling, which can be used in semiconductor devices.
