This invention relates to the modification of elastomers especially epoxidised rubber by reaction with unsaturated silanes, to the modified elastomers produced and to articles produced by shaping and curing modified elastomer compositions. In a process according to the present invention, the silane has the formula: R''-CH=CH-C(O)X-Y-SiR a R' (3-a) (I) or R"-C≡C-C(O)X-Y-SiR a R' (3-a) (II) in which R, R' a, Y, X and R" are as defined in the description. |
