Claim 1
Independent Claim
130 words
A vibration damping metal panel comprising two metal plates and an intermediate layer interposed therebetween, wherein said intermediate layer is composed of: (A) 1-90% by weight of at least one rubbery polymer having in its molecule an α,β-unsaturated carboxylate group represented by the following general formula: ##STR2## wherein X is a halogen atom selected from the group consisting of Cl, Br and I, each of R 1 , R 2 and R 3 is a hydrogen atom or a hydrocarbon residue having a carbon number of 1-10, n is an integer of 2-5, m is an integer of 1-4 and 1 is an integer of 1-30, and (B) 99-10% by weight of a substance selected from polymerizable monomers and mixtures thereof, and wherein said intermediate layer is cured by heating.
Claim 2
Dependent Claim
130 words
A vibration damping metal panel comprising two metal plates and an intermediate layer interposed therebetween, wherein said intermediate layer is composed of: (A) 1-90% by weight of at least one rubbery polymer having in its molecule an α,β-unsaturated carboxylate group represented by the following general formula: ##STR2## wherein X is a halogen atom selected from the group consisting of Cl, Br and I, each of R 1 , R 2 and R 3 is a hydrogen atom or a hydrocarbon residue having a carbon number of 1-10, n is an integer of 2-5, m is an integer of 1-4 and 1 is an integer of 1-30, and (B) 99-10% by weight of a substance selected from polymerizable monomers and mixtures thereof, and wherein said intermediate layer is cured by heating.
Claim 3
Dependent Claim
68 words
The vibration damping metal panel according to claim 1, wherein said intermediate layer further contains 1-100 parts by weight of an inorganic or organic filler, 1-100 parts by weight of a tackifier, 1-50 parts by weight of conductive particles or mixtures thereof, based on 100 parts by weight of the sum of said components (A) and (B), and wherein said intermediate layer has a thickness of 0.01-1.0 mm.
Claim 4
Dependent Claim
34 words
The vibration damping metal panel according to claim 1, wherein said α,β-unsaturated carboxylic group is introduced in the rubber polymer at a ratio of one group per molecular weight of the polymer of 100-10,000.
Claim 5
Dependent Claim
34 words
The vibration damping metal panel according to claim 3, wherein said α,β-unsaturated carboxylic group is introduced in the rubbery polymer at a ratio of one group per molecular weight of the polymer of 100-8,000.
