Laminar articles from a polyolefin matrix, ethylene-vinyl alcohol copolymers and a compatibilizer |
摘要 |
The laminar article of the invention comprises a mixture of a polyolefin matrix with a barrier resin of polyethylene-vinyl alcohol copolymer and a compatibilizer selected from an ethylene-ethylenically unsaturated carboxylic acid copolymer such as ethylene methacrylic acid or ethylene acrylic acid, ethylene vinyl acetate, polyethylene vinyl alcohol or mixtures thereof. A process is also claimed for preparing a laminar article with multiple thin, overlapping layers, comprising preparing a melted heterogeneous blend of a polyolefin, an ethylene-vinyl alcohol copolymer, and the above compatibilizer; extending the body of the melt; and cooling the extended body to below the melting point of the polyolefin. |
