Abstract
L'invention concerne un film polymère, préparé à partir d'un polymère thermosensible, pouvant être jeté dans les toilettes et présentant une résistance améliorée lorsqu'il est plongé dans l'eau. Ce film peut être utilisé dans un produit absorbant jetable, pour que le produit puisse être jeté dans les toilettes après usage, et confère la résistance désirée audit produit, pendant son utilisation. L'invention concerne également un procédé de préparation desdits polymères thermosensibles. Ce procédé consiste à préparer le polymère thermosensible dans une solution aqueuse au moyen d'un agent de migration de chaîne.
