A diene polymer having excellent heat resistance and a method for producing the same. A polymer containing a unit represented by the following formula (1) and a method for producing the polymer. (In the above formula (1), X 1 and X 2 each independently represent an atom of Group 16 of the periodic table of the elements; Y 1 and Y 2 each independently represent an amino group, an amide group, an imide group; Y 1 and Y 2 may be bonded to each other to form a ring; A 1 , A 2 , A 3 , A 4 , A 5 , A 6 , A 7 , A 8 , A 9 and Each A 10 is independently a hydrogen atom, halogen atom, alkyl group, aralkyl group, aryl group, silyl group, siloxy group, alkoxy group, aralkyloxy group, aryloxy group, amino group, amide group, imide group, or carbonized Represents a hydrogen thio group; m represents 0 or 1; and n represents an integer of 1 to 20.)
