Abstract: A process has been developed for directly producing a modified polyolefin composition in particulate form which has improved adhesiveness. Generally, the process comprises providing an olefin polymer in particulate form; admixing the olefin polymer, an organic peroxide and a specific polymerizable compound generally defined by the formula ; REACTING THE MIXTURE IN AN INERT ATMOSPHERE AT A TEMPERATURE BELOW THE TACKY POINT OF THE POLYMER; AND DIRECTLY RECOVERING THE MODIFIED POLYOLEFIN COMPOSITION.
