Basis of Solid-Phase Grafting of Polypropylene

Abstract

Abstract The chemical modification of polymers opens new dimensions for the development and design of materials based on plastics. The chemical modification of polymers by reactions is performed by reactions in a melt, in a solution, or in a solid phase. The modification of polymers in solid phases (powder or granular material directly from the polymerization) has great advantages compared with reactions in solution or melt. The advantages are lower costs and, most important, greater creative variability. A special advantage of solid-phase modification of polypropylene (PP) is the fact that the degradation reaction is reduced.
