Process for grafting maleic anhydride onto unsaturated polyolefinic elastomers. |
摘要 |
Maleic anhydride is grafted onto unsaturated elastomeric polymers comprising units derived from at least two different monomers of general formula R-CH = CH2 (R = hydrogen or an alkyl group containing from 1 to 6 carbon atoms) and from conjugated or non-conjugated dienes by reaction in mass, carried out by heating a mixture of said anhydride with the polymer in the presence of a catalyst of formula: MnXz (I) wherein: M = a metal of group VIII of the periodic system, in particular Rh and Ru; X = a counterion; n = valence of the counterion; z = valence of the metal. c |
