Abstract:
    A functionalised elastomer (EF) consisting of an elastomeric substrate with a weight-average molecular weight (a) of 10000-600000 daltons and a polydispersity index lower than 5, and having grafted thereon 0.1-10 wt.%, based on the weight of the substrate, of sequences (b) wherein R1 is a C1-12 (x z 1)-valent hydrocarbon radical, X is H or a C1-12 monovalent hydrocarbon radical R, z is 0 or 1 and x is an integer from 1 to 3, where x z
