Abstract
The invention relates to the use of polyolefins modified with one or more silanes as adhesion promoters for the production of flat glass/glass, glass/plastic, or plastic/plastic laminates, to corresponding laminates, and to displays containing the laminates according to the invention.
Claims20
A laminate comprising:
- a flat glass body;
- a body applied to at least one side of the flat glass body;
- and
- an intermediate adhesion promoter layer between the flat glass body and the applied body;
- wherein
- the body applied to the flat glass body is glass, plastic or a mixture thereof, and
- the intermediate adhesion promoter layer comprises at least one silane modified polyolefin, the polyolefin being a polyethylene-co-propylene-co-1-butene) comprising:
- 2 to 25% by weight ethene;
- 50 to 80% by weight propene;
- and
- 7 to 98% by weight of butene
- wherein said polyolefin has a propylene fraction of from 50 to 80 ma % and a solubility in tetrahydrofuran at room temperature of at least 70 ma %.

A laminate comprising:
- at least one flat plastic body of a first plastic;
- a body applied to at least one side of the flat plastic body;
- and
- an intermediate adhesion promoter layer between the flat plastic body and said body;
- wherein
- said body is of the same plastic or a plastic different from the first plastic of said flat plastic body, and
- the intermediate adhesion promoter layer comprises at least one silane modified polyolefin, the polyolefin being a poly(ethylene-co-propylene-co-1-butene) comprising:
- 2 to 25% by weight ethene;
- 50 to 80% by weight propene;
- and
- 7 to 98% by weight of butene
- wherein said polyolefin has a propylene fraction of from 50 to 80 ma % and a solubility in tetrahydrofuran at room temperature of at least 70 ma %.
