Abstract:
1. A conjugated diene based polymer comprising a monomer unit derived from a noncyclic conjugated diene and a monomer unit derived from an alicyclic hydrocarbon compound having a non-conjugated carbon-carbon double bond, wherein the alicyclic hydrocarbon compound having a non-conjugated carbon-carbon double bond is a compound represented by formula (1), wherein R 1 , R 4 , and R 8 each independently represent a methine group or a carbon atom, R 2 , R 3 , R 5 , and R 6 each independently represent a group represented by —C(R 11 )(R 12 )—, wherein R 11 and R 12 each independently represent a hydrogen atom or a hydrocarbyl group having 1 to 10 carbon atoms, or a group represented by —CH═, R 7 and R 9 each independently represent a hydrocarbyl group having 1 to 10 carbon atoms or a group represented by ═C(R 13 )(R 14 ), wherein R 13 and R 14 each independently represent a hydrogen atom or a hydrocarbyl group having 1 to 10 carbon atoms, and R 10 represents a hydrocarbyl group having 1 to 10 carbon atoms.
