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; Y 1 and Y 2 each independently represent an alkoxy group, an aralkyloxy group or an aryl group. Represents an oxy group, and 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 A 10 are each 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 a hydrocarbon thio group, A 3 and A 4 , or A 5 and A 6 may be bonded to each other to form a ring; n represents an integer of 1 to 20.)
