An elastic laminate is provided which has an elastic layer and one or two outer facing layers. The elastic layer is formed from an improved styrene-(ethylene-butylene)-styrene-(ethylene-butylene) tetrablock copolymer, or a blend of the copolymer. The copolymer has a number average molecular weight of at least about 70,000. The two ethylene-butylene blocks have number average molecular weights which together constitute more than 75% of the number average molecular weight of the copolymer. |
