Abstract
The present invention relates to new tie-layer materials for making (1) new multilayer structures formed from one or more ionomers and one or more new tie-layers including a (co) extrudable tie resin (CTR), and optionally a backing layer to form laminates, (2) new composite articles made from these laminates in combination with optional substrate materials, and (3) new methods of making composite articles from these laminates by shaping and subsequently contacting them with a substrate material.
Claims20
A laminate comprising:
- an ionomer layer and
- a tie-layer comprising a (co)extrudable tie resin (CTR), wherein the CTR consists essentially of a copolymer of one or more C2-C10 α-olefins and one or more ethylenically copolymerizable amine-containing monomers, the copolymer having amine groups that may be represented by the general formula:
- where each R is independently H or a C1 to C10 hydrocarbon and R′ is a bond or a C1 to C10 hydrocarbon.
A composite comprising:
- an ionomer layer;
- a tie-layer comprising a (co)extrudable tie resin (CTR);
- and
- a substrate, wherein the CTR consists essentially of a copolymer of one or more C2-C10 α-olefins and one or more ethylenically copolymerizable amine-containing monomers, the copolymer having amine groups that may be represented by the general formula:
- where each R is independently H or a C1 to C10 hydrocarbon and R′ is a bond or a C1 to C10 hydrocarbon.

A composite article formed by the method comprising:
- (a) providing a laminate comprising an ionomer layer and a tie-layer comprising a (co)extrudable tie resin (CTR);
- (b) forming a shape from the laminate, resulting in a shaped laminate;
- and
- (c) securing a substrate material to the shaped laminate, wherein the CTR consists essentially of a copolymer of one or more C2-C10 α-olefins and one or more ethylenically copolymerizable amine-containing monomers, the copolymer having amine groups that may be represented by the general formula:
- where each R is independently H or a C1 to C10 hydrocarbon and R′ is a bond or a C1 to C10 hydrocarbon.
