The present invention relates to improved liquid absorbing thermoplastic materials useful for example as absorbent materials for disposable absorbent articles. The liquid absorbing thermoplastic materials comprise A) thermoplastic compositions comprising thermoplastic polymers and suitable compatible plasticisers and B) superabsorbent particles dispersed in the thermoplastic compositions. Such liquid absorbing thermoplastic material, preferably in form of hot melt compositions, can be utilised in the absorbent cores of disposable absorbent articles, such as sanitary napkins, panty liners, disposable diapers, nursing pads and the like for completely or partially substituting said absorbent cores.
L'invention concerne des matériaux thermoplastiques à absorption de liquide améliorés, utiles, par exemple, comme matériaux absorbants pour des articles absorbants jetables. Les matériaux thermoplastiques à absorption de liquide comprennent A) des compositions thermoplastiques comprenant des polymères thermoplastiques et des plastifiants compatibles appropriés et B) des particules très absorbantes dispersées dans les compositions thermoplastiques. Un tel matériau thermoplastique à absorption de liquide, de préférence, sous forme de compositions fusionnées, peut être utilisé dans les noyaux absorbants d'articles absorbants jetables, tels que des serviettes hygiéniques, des protège-slips, des langes jetables, des coussinets d'allaitement et analogue, aux fins de substitution complète ou partielle desdits noyaux absorbants.
