Abstract
A single-strand cord rubberized in situ (C) comprising: an internal layer of the cord (CT1) comprising N1 internal thread(s), an external layer of the cord (CT3) comprising N3 external threads wound helically around the internal layer of the cord, a rubber composition (20) positioned between the internal layer of the cord and the external layer of the cord. The rubber composition (20) comprises a compound of formula (I) or (II) or a salt of this compound: in which each R1, R2, R3 and R4 group represents, independently of one another, an —OH, —O-Alkyl or —O(C)O-Alkyl group.
