摘要： Disclosed are propylene-based polymers with improved melt strength, improved strain hardening characteristics and processes for producing the same. The processes include reacting a polyamine with a maleic anhydride-grafted-propylene-based polymer. The processes produce a rheology-modified propylene-based polymer with long chain branching by forming a polyimide linkage which couples polymer chains of the propylene-based polymer. The polyimide-coupled propylene-based polymer exhibits improved melt strength and improved strain hardening characteristics.

摘要： The present invention discloses a process for forming a biaxially oriented film. The process includes first selecting a polyolefin resin wherein said polyolefin resin comprises a linear low density polyethylene resin characterized by having from 9 to 35 weight percent of the total weight of linear low density polyethylene resin eluting from a CEF at a temperature greater than 97.0° C.; and further characterized by having a CDR of from 33 to 80 and a Mw Ratio of from 0.15 to 0.45. Next a film is formed from the polyolefin resin selected in the first step. Finally the film formed in the second step is oriented in a sequential manner. The films produced by this process are characterized by having an ultimate elongation at least 1.5 times greater in the MD as compared to the CD and the 2% secant modulus is a least 1.25 times greater in the CD as compared to the MD. The films are further characterized by having free residual shrinkage of less than 10% in the MD and less than 10% in the CD when exposed to a temperature of 90° C. for 10 minutes.
