BARRIERS FOR INJECTION MOLDED PLASTIC PREFORMS OR CONTAINERS AND INJECTION MOLDED PLASTIC PREFORMS OR CONTAINERS MADE THEREWITH

摘要

A barrier for injection molding, the barrier including a manganese (Mn) catalyst and an oxygen barrier. In embodiments, the oxygen barrier comprises MXD6. Such barriers may be included with a polymer to form a composition used in an injection process. In other embodiments, a barrier includes a transition metal catalyst, an organic compound, and a radical initiator. In embodiments, the radical initiator comprises one or more azo-compounds or peroxides. Plastic preforms and containers that are injection molded with such barriers/compositions are also disclosed.
