Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
73 words
A laminated structure comprising at least one metal and at least one polybutylene layers and an adhesive layer between the metal and polybutylene layers, said adhesive consisting essentially of a hydrogenated block copolymer having at least one block comprised primarily of a monoalkenyl aromatic hydrocarbon monomer and at least one block comprised predominantly of a hydrogenated conjugated diolefin monomer, said block copolymer which is further modified by reacting with a maleic acid compound.
Claim 2
Dependent Claim
73 words
A laminated structure comprising at least one metal and at least one polybutylene layers and an adhesive layer between the metal and polybutylene layers, said adhesive consisting essentially of a hydrogenated block copolymer having at least one block comprised primarily of a monoalkenyl aromatic hydrocarbon monomer and at least one block comprised predominantly of a hydrogenated conjugated diolefin monomer, said block copolymer which is further modified by reacting with a maleic acid compound.
Claim 3
Dependent Claim
14 words
The laminated structure of claim 1 wherein said functionalized block copolymer is acid modified.
Claim 4
Dependent Claim
14 words
The laminated structure of claim 1 wherein said maleic acid compound is maleic anhydride.
Claim 5
Dependent Claim
11 words
The laminated structure of claim 1 wherein the metal is steel.
Claim 6
Dependent Claim
11 words
The laminated structure of claim 1 wherein the metal is aluminum.
Claim 7
Dependent Claim
16 words
The laminated structure of claim 1 wherein the block copolymer is a styrene-hydrogenated butadiene-styrene block copolymer.
Claim 8
Dependent Claim

Claim 11
Dependent Claim
50 words
The laminated structure of claim 1 wherein said adhesive is a blend containing a hydrogenated triblock copolymer, said triblock copolymer which is further modified by reacting with a maleic acid compound and a hydrogenated diblock copolymer, said diblock copolymer which is further modified by reacting with a maleic acid compound.
Claim 12
Dependent Claim
18 words
The laminated structure of claim 1 wherein said polybutylene has a melt flow of between 0.2 and 300.
Claim 13
Dependent Claim
