Abstract
Abstract A composition comprising at least one sulfur-vulcanizable rubber, this composition being intended to adhere to at least one metallic surface during the course of vulcanization, is characterized by the fact that it further comprises from 0.1 to 2 parts by weight of nickel, present in the form of nickel (II) acetylacetonate, per 100 parts by weight of rubber.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
123 words
An assembly comprising at least one rubber composition and at least one solid body at least the surface of which is zinc or brass, the rubber composition being in contact with the solid body wherein the rubber composition is characterized by the following features and properties: (a) it comprises a basic formulation containing at least one sulfur-vulcanizable rubber and from 1 to 10 parts by weight of sulfur, per 100 parts by weight of rubber; (b) it further comprises from 0.1 to 2 parts by weight of nickel, present in the form of nickel (II) acetylacetonate, per 100 parts by weight of rubber; (c) the rubber composition and the basic formulation have substantially the same hysteresis loss when vulcanized under the same conditions.
Claim 2
Dependent Claim
123 words
