Abstract
A reaction product of a diolefine polymer with a phenol and an olefinically unsaturated carboxylic acid or its anhydride wherein the diolefine polymer is PA0 (a) a homopolymer of a diene having 4 to 10 carbon atoms, PA0 (b) a copolymer of at least two dienes of (a), PA0 (c) a copolymer of at least one diene of (a) with a minor molar amount of at least one copolymerizable monomer, PA0 (d) a combination of at least two of (a) to (c) Wherein the amount of phenol is in the range from 2 to 40% by weight and the amount of the unsaturated carboxylic acid or its anhydride is in the range from 2 to 55% by weight, always referred to the starting polymer, a process for the preparation of said product wherein PA0 (a) a homopolymer of a diene having 4 to 10 carbon atoms, PA0 (b) a copolymer of at least two dienes of (a), PA0 (c) a copolymer of at least one diene of (a) with a minor molar amount of at least one copolymerizable monomer, PA0 (d) a combination of at least two of (a) to (c), PA0 (e) polymerizable unsaturated monomers being the base for one of polymers (a) to (c) either alone or in admixture are polymerized and at the same time the reaction mass Is reacted in one step with an amount …
