Coupling agent of formula (I) for better adhesion between a vulcanisable polymer and a metallic reinforcement. X-(R)n-(Ar)i-(R)m-Y (I) in which X = SH, SiCl3, SiR1Cl2, Si(OR1)3, SiR1(OR1)2, COOH or COCl (with R1 = linear or branched alkyl); R = CH2, CF2, CH2-CO-NH-CH2, CF2-CO-NH-CF2, CH2-CO-NH-CF2 or CF2-CO-NH-CH2, with n = 0 or more and m = at least 16; Ar = unsubstituted or substituted aromatic and/or heteroaromatic system, with i = 0-6; Y = unsaturated group, with n = m = i = not zero. Also claimed is (i) a metallic reinforcement coated with (I) for bonding with vulcanisable polymer, and (ii) a composite system comprising vulcanisable polymer, coupling agent (I) and metallic reinforcement. |
