CA 2275386

A thermoplastic film comprises a polyolefin, such as polyethylene, as a major constituent, poly(ethylene oxide) as a minor constituent and has a total of from about 0.1 weight percent to about 30 weight percent of monomer grafted to the polyolefin and the poly(ethylene oxide). The film exhibits an inverse phase morphology so that the poly(ethylene oxide) forms a continuous phase and the polyolefin forms a dispersed or discontinuous phase in the film. Desirably, the film can be used in disposable personal hygiene articles.

Film thermoplastique qui comporte une polyoléfine, telle que le polyéthylène, comme composant principal, un poly(éthylène oxyde) comme composant minoritaire et qui possède une quantité totale de monomère greffé à la polyoléfine et au poly(éthylène oxyde) située entre environ 0,1 % en poids et environ 30 % en poids. Le film présente une morphologie en phase inversée afin que le poly(éthylène oxyde) constitue une phase continue et que la polyoléfine constitue une phase dispersée ou discontinue dans le film. Le film peut être utilisé de préférence dans des articles d'hygiène personnelle jetables.
