UNIQUE MOLECULAR WEIGHT DISTRIBUTION POLYBUTYLENE BLEND AND FILM Abstract of the Invention An unusual polybutene-1 polymer blend based on the ability of polybutene-1 to undergo random scission of molecules in a chemical cracking process. Such cracked polymer when blended back with the parent polybutene-1 produces a unique molecular weight distribution which is manifested in a unique and valuable combination of processing behavior and mechanical, optical and thermal properties of film made from the blend. Good hot tack, low heat sealing temperature and high clarity as well as improved processability are simultaneously achieved in these films.
