Barrier resins and impact modifiers therefor |
| abstract |
Polymers having low permeability to gases and vapors and yet high heat stability and creep resistance are prepared by a novel method of polymerizing acrylonitrile, a vinylidene aromatic monomer such as styrene and an olefinic ester such as methyl methacrylate. Conjugated diene-based impact modifiers for said polymers are disclosed, as well as impact-resistant blends of said polymers and said impact modifiers. The blends are useful for packaging materials in applications wherein high thermoformability and processability, as well as excellent barrier properties and heat stability, color stability, and creep resistance are desired. |
