Abstract
Polymers resulting from the association of two reactive components having a low melt viscosity, characterized in that one of the components is a polypropylene modified by grafting an unsaturated monomer bearing an acid anhydride group and the other is a compound R posessing at least two groups which are reactive towards this anhydride group. Uses in the manufacture of moulded articles by the reaction-injection-moulding technique, or in the manufacture of composite materials. Uses as coatings for metallic articles.
