The present invention relates to a single- or multilayer product containing &agr;-olefin-vinyl alcohol copolymers and at least one &agr;-olefin-vinyl acetate copolymer, wherein the amount of vinyl acetate repeat units present in the &agr;-olefin vinyl acetate copolymer is in the range from 35 to 99.99% by weight, and these repeat units have good flexibility which permits processing films or other thin-walled items which are transparent after stretching or thermoforming, and to a process for producing the same, and to their use as packaging films.

EVOH and EVM in single- or multilayer products

Described is a molded plastic article which includes a barrier film. The molded plastic article is prepared by a process which involves: (a) providing a barrier film comprising at least one polymeric layer, the barrier film having a first surface and a second surface; (b) placing the barrier film in a mold such that the first surface of the barrier film is in contact with at least a portion of the interior surfaces of the mold; (c) injecting a polymer (e.g., a molten thermoplastic polymer) into the mold, the injected polymer contacting the second surface of the barrier film; and (d) removing the molded plastic article from the mold. Also described are molded articles according to the present invention, which include, for example, plastic containers, plastic fuel tanks, plastic storage units, plastic fascias and plastic motor vehicle interior cladding materials.

Molded plastic article comprising a barrier film

The invention relates to transparent multi-layer films made from polyamides and polyolefines using copolyamides of .epsilon.-caprolactam together with diamines and dicarboxylic acids.

Multi-layer films made from copolyamides

The invention relates to a process for the production of high molecular weight polyamide 6 (polycaprolactam).

Process for the production of high molecular weight polyamide 6

This invention relates to a process for the preparation of particulate, high molecular weight polyamides, to the particulate, high molecular weight polyamides prepared by this process, to the use of these polyamides for the production of moulded bodies, especially by extrusion or blow moulding, and to the articles produced from the polyamides according to the invention. The process is characterized in that polyamides are mixed with concentrates of certain compounds containing phosphorus and worked up into granulates and these granulates are converted into high molecular weight products by solid phase after-condensation.

Process for the preparation of high molecular weight polyamides

The invention relates to high molecular weight (co)polyamides and to a process for the accelerated production of polyamides during melt polycondensation using a combination of aminocaprolactam (ACL) and/or lysine components and polycarboxylic acids and known catalysts and also, if desired, for the accelerated solid-phase post-condensation of the catalyst-containing (co)polyamides and to the polyamides produced by the processes.

Melt preparation of polyamide with additive combination

This invention relates to a process for the production of shrinkable sheet products from copolyamides with good processing properties. The copolyamides consist of .epsilon.-caprolactam and equimolar quantities of dimeric fatty acids and diamines.

Process for the production of polyamide sheet products

A method of producing polyamide foils by extrusion wherein a dispersion of a solid inorganic nucleating agent is added to the polyamide.
