More Information
Summary:The invention concerns a certain class of polymers, their production into fi lms and applications for their use. These polymers have unique properties which make them particularly well suited for use in polyme ric films. These films are very useful in applications requiring heat sealability, particularly those applications containing an ionomer fil m. It has been discovered that polymers derived from met allocene catalyst systems surprisingly heat seal extremely well, as compared to polym er produced by conventional Ziegler-Natta catalysts, to a class of polymers known as ionomers.
