Abstract
Laminate structures comprising one or more sheets of material bonded together with an adhesive polymer. The adhesive polymer is a polyester amide, polyester urethane, or polyester urea.
Claims14
A laminate structure comprising two or more sheets of glass and an adhesive polymer disposed between the sheets of glass, wherein the adhesive polymer comprises a poly(ester amide) that is a self assembling material;
- wherein
- the poly(ester amide) has the formula:
- wherein paired brackets contain respective x and y repeat units, wherein each x and y independently is an integer of 1 or higher that represents the number of one of the respective x and y repeat units;
- R is independently in each occurrence an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- R′ is a C2-C12 alkylene;
- R″ is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- and
- Ra is a bond or is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- or
- wherein
- paired brackets contain respective x and y repeat units, wherein each x and y independently is an integer of 1 or higher that represents the number of one of the respective x and y repeat units;
- R is independently in each occurrence an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- R′ is a bond or a C2-C12 alkylene group;
- R″ is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- and
- Ra is a bond or is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- wherein the number average molecular weight of the adhesive polymer is between 8,000 and 20,000 g/mol.
A laminate structure consisting of one sheet of glass and an adhesive polymer, the sheet of glass having a surface and the adhesive polymer coating a substantial portion of the surface of the sheet of glass, wherein the adhesive polymer comprises a poly(ester amide) that is a self assembling material;
- wherein the poly(ester amide) has the formula:
- wherein
- paired brackets contain respective x and y repeat units, wherein each x and y independently is an integer of 1 or higher that represents the number of one of the respective x and y repeat units;
- R is independently in each occurrence an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- R′ is a C2-C12 alkylene group;
- R″ is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- and
- Ra is a bond or is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- or
- wherein
- paired brackets contain respective x and y repeat units, wherein each x and y independently is an integer of 1 or higher that represents the number of one of the respective x and y repeat units;
- R is independently in each occurrence an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- R′ is a bond or a C2-C12 alkylene group;
- R″ is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- and
- Ra is a bond or is an aliphatic or heteroaliphatic, alicyclic or heteroalicyclic or aromatic or heteroaromatic group;
- wherein the number average molecular weight of the adhesive polymer is between 8,000 and 20,000 g/mol.
