METODO DE PREPARAR ESTRATIFICADOS DE POLIMEROS FUNCIONALIZADOS CON GRUPO IMINO-ETER CICLICOS COLGANTES Y GRUPOS COREACTIVOS QUE CONTIENEN HIDROGENO ACTIVO.

摘要

A method for preparing a polymeric laminate by the reactive coextrusion of functionalized polymers wherein at least one layer is a polymer having functional groups and the adjacent layer is a polymer having coreactive groups which form covalent bonds with the functional groups at the interfacial surfaces. One such functional group can comprise a pendant cyclic imino ether group to form covalent bonds with the coreactive groups. A laminate having a plurality of layers covalently bonded together through the interaction of pendant cyclic imino ether groups and coreactive groups is also provided.
