Title
(EN) STABILIZATION OF INCOMPATIBLE MATERIALS BY MACROMOLECULES
(FR) STABILISATION DE MATIERES INCOMPATIBLES PAR DES MACROMOLECULES
Abstract
(EN)
A stable dispersion of polyethylene and other polyolefins in a continuous bituminous phase is provided by dissolving macromolecular material into the bitumen to create a potential energy barrier to coalescence and flocculation of the polymer dispersion.
(FR)
La présente invention concerne une dispersion stable de polyéthylène et d'autres polyoléfines dans une phase bitumineuse continue, dispersion stable obtenue grâce à la dissolution de matière macromoléculaire dans le bitume afin de créer une barrière d'énergie potentielle à l'agglomération et à la floculation de la dispersion polymère.
