Films blown by the inflated bubble method of alloys of vinylidene chloride interpolymers and olefin polymers

Blends of a vinylidene chloride polymer, an olefin polymer, and a compatibilizer polymer are successfully fabricated into films using the well-known inflated bubble technique, by using blow-up rates in the range of about 1.5 to 5.0 and a drawn-down ratio upwards of 6, preferably upwards of 8, but no...

Beschreibung
Zusammenfassung:Blends of a vinylidene chloride polymer, an olefin polymer, and a compatibilizer polymer are successfully fabricated into films using the well-known inflated bubble technique, by using blow-up rates in the range of about 1.5 to 5.0 and a drawn-down ratio upwards of 6, preferably upwards of 8, but not exceeding the critical draw-down ratio of 13. At a draw-down ratio exceeding 13, the physical properties of the polymer blend are seriously diminished.
