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.
