Abstract

L'invention est relative à des articles en mousse expansée du type de ceux décrits dans le brevet principal n degrés 77 02924. L'agent porogène utilisé dans ces articles répond à la formule R'1 - CF2 - R'2 dans laquelle R'1 désigne dichlorométhyle et R'2 désigne hydrogène, chlore, fluor, méthyle, trifluorométhyle et lorsque R'2 désigne trifluorométhyle, R'1 désigne méthyle, éthyle, chlorométhyle, difluorométhyle, chlorofluorométhyle, fluorométhyle, trifluorométhyle. Ces articles en mousse ont des propriétés d'isolation et de stabilité dimensionnelle améliorées.
