    Abstract: 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.

    Abstract: A multicomponent polymer blend composition is prepared by intimately mixing a thermoplastic polyester, a selectively hydrogenated monoalkenyl arene-diene block copolymer, and at least one dissimilar engineering thermoplastic resin under such conditions that at least two of the polymers form at least partial continuous network phases which interlock with the other polymer networks and therefore results in a desirable balance of properties. These blends have an unobviously high heat distortion temperature relative to the improved impact strength.
