VERBESSERTE LAMINARE GEGENSTÄNDE AUS POLYOLEFIN UND EINER NYLON/PVOH-MISCHUNG

摘要

A laminar shaped article which exhibits substantial improvement in the fluid barrier properties over the laminate of the prior art. The article comprises a heterogeneous blend of: (a) polyolefin with (b) a melt blend of a nylon and a polyvinyl alcohol component, and a compatibilizer(c), which is either: i) a mixture of two different alkylcarboxyl-substituted polyolefins which serves as a compatibilizer; or ii) a small amount of alkylcarboxyl-substituted polyolefin with a small amount of grafted maleic anhydride moieties; or iii) a high weight percent of alkylcarboxyl-substituted polyolefin with a high graft level of grafted maleic anhydride moieties.
