Title:
共押出し可能な多層ポリマー
Document Type and Number:
Japanese Patent JP2006511363
Kind Code:
A
Abstract:
The present invention provides a multi-layer polymer composition having a polar outer layer and a non-polar second outer layer. The polar outer layer is preferably PVC and the non-polar outer layer, polypropylene. The adhesive tie layer is a unique blend of a copolyester elastomer, a non-polar polymer, and a copolymer that contains functional groups capable of reaction with the functional end groups of the copolyester elastomer and that is totally or partially miscible with the non-polar polymer in the second outer layer. The multi-layer polymer can be advantageously coextruded. The non-polar outer layer can comprise the bulk of a fabricated part, with only a thin layer of polar polymer, providing desired attributes of the polar polymer at a lower cost.
