The invention relates to providing elastication in defined areas of an article by applying a thermoplastic elastomeric composition under elastic tension to the article and deactivating or partially deactivating elastic tension in the composition outside the said defined areas. Elastic tension may be deactivated by (i) heating to a temperature of at least the inversion temperature between G' and G"; or (ii) heating to a temperature below the inversion temperature between G' and G" with application of a pressure equal to at least the value of G' at that temperature. The article may be an absorbent article, such as a disposable diaper and elastic tension may be retained in the crotch area and deactivated outside the crotch area. Alternatively the thermoplastic elastomeric composition may be applied to the article as a thread or strip and subjected to complete or partial deactivation of elastic tension at a series of points along the length of the thread or strip in order to improve adhesion to the article.
