    摘要: A vulcanized rubber composition which is obtained by vulcanizing a modified ethylene-.alpha.-olefin-nonconjugated diene copolymer rubber composition defined below with sulfur or organic peroxides, said modified rubber composition comprising an ethylene-.alpha.-olefin-nonconjugated diene copolymer rubber modified with 0.01-0.15% by weight of an unsaturated carboxylic acid or a derivative thereof on the basis of the modified ethylene-.alpha.-olefin-nonconjugated diene copolymer rubber and at least one dinitroamine represented by the following formula (A): ##STR1## wherein X represents a divalent chain aliphatic, cyclic aliphatic or aromatic group which may contain a halogen or oxygen, R.sup.1 represents a hydrogen atom, a chain aliphatic group, a cyclic aliphatic group or an aromatic group with a proviso that when both X and R.sup.1 represent a chain aliphatic group, nitrogen atoms may further link to each other through R.sup.1, and R.sup.2 and R.sup.3 each represents a hydrogen atom or an alkyl group of 1-12 carbon atoms and R.sup.2 and R.sup.3 may link to each other to form a ring. The vulcanized rubber composition is excellent in fatigue resistance against repeatedly applied deformation.

    摘要: It is an object of the present invention to provide a speaker edge which is high in strength, less in scattering of f0, high in waterproofness, small in amplitude at the time of resonance, easy to mold, and easy to be integrated with a cone body. That is, the present invention provides a speaker edge constituted by a molding which is molded in a manner so that a speaker edge raw material composition containing isocyanate and polyol is injected into a cavity of a mold by an agitating/mixing apparatus and subjected to reaction, foaming and curing in the cavity.
