COMPATIBILIZED POLYESTER/POLYAMIDE BLENDS

摘要

Disclosed are compatibilized polymer blends comprising polyester, polyamide and a compatibilizer. Such compatibilized polymer blends, in preferred embodiments, are fabricated into monolayer or multilayer preforms and/or containers. Containers comprising such blends exhibit good gas barrier properties against gases such as oxygen and carbon dioxide, have a good appearance and may be used as containers for a wide variety of consumer products, including beverages, edibles and cosmetics. In multilayer containers comprising one or more layers of the compatibilized polymer blend and one or more layers of PET or PET-containing copolymers, the present containers have greatly improved impact delamination resistance as compared to those formed using uncompatibilized blends.
