A sulfur-modified polychloroprene, comprising functional groups having a structure represented by Chemical Formula I (in Chemical Formula I, R0 represents an alkyl group having 1 to 4 carbon atoms and x is an integer of 2 to 8) in an amount of 0.05 to 0.

Abstract: A binding tool having a main member and a lateral member for clamping a bundle of cables between a bottom portion of the main member and a lateral bar of the lateral member. A first guide groove and a second guide groove are provided on a first arm portion of the main member and a first insertion hole into which the first arm portion can be inserted is provided on the lateral bar of the lateral member. On portions of the inner face of the first insertion hole corresponding to the first guide groove and the second guide groove, a first engaging protrusion and a second engaging protrusion extending longitudinally are provided, respectively. Both left and right faces of the first engaging protrusion and both left and right faces of the second engaging protrusion are guided in the first guide groove and the second guide groove, respectively.
