Formable thermoplastic multi-layer laminate, a formed multi-layer laminate, an article, and a method of making an article
View Patent ↗Disclosed is a formable thermoplastic multi-layer laminate comprising an outer layer comprising a polymer comprising resorcinol arylate polyester chain members, a middle layer comprising a thermoplastic polymer, an inner-tie layer comprising a thermoplastic polymer comprising a carbonate polymer and an acrylonitrile-styrene graft copolymer comprising at least one of an acrylonitrile-styrene-acrylate graft copolymer (ASA) or an acrylonitrile-butadiene-styrene graft copolymer (ABS), the middle layer being between the outer layer and the inner-tie layer and being in contact with both the outer layer and the inner-tie layer. Also disclosed are a formed multi-layer laminate and an article comprising the multi-layer laminate bonded to a substrate. A method of making the article is also disclosed.
1. A formable thermoplastic multi-layer laminate comprising
an outer layer comprising a polymer comprising resorcinol arylate polyester chain members,
a middle layer comprising a thermoplastic polymer, and
an inner-tie layer comprising a thermoplastic polymer comprising a carbonate polymer and an acrylonitrile-styrene graft copolymer comprising at least one of an acrylonitrile-styrene-acrylate graft copolymer (ASA) or an acrylonitrile-butadiene-styrene graft copolymer (ABS),
the middle layer being between the outer layer and the inner-tie layer and being in contact with both the outer layer and the inner-tie layer.
2. The multi-layer laminate of claim 1 wherein the outer layer has a thickness about 3 to about 30 mils.
3. The multi-layer laminate of claim 1 wherein the acrylonitrile-styrene graft copolymer comprises an acrylonitrile-styrene-acrylate graft copolymer (ASA).
4. An article comprising
a formable thermoplastic multi-layer laminate comprising
an outer layer comprising a polymer comprising resorcinol arylate polyester chain members,
a middle layer comprising a thermoplastic polymer,
an inner-tie layer comprising a thermoplastic polymer comprising a carbonate polymer and an acrylonitrile-styrene graft copolymer comprising at least one of an acrylonitrile-styrene-acrylate graft copolymer (ASA) or an acrylonitrile-butadiene-styrene graft copolymer (ABS),
the middle layer being juxtaposed between the outer layer and the inner-tie layer and being in continuous contact with both the outer layer and the inner-tie layer, and
a substrate bonded to the inner-tie layer.
