Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
41 words
Metallized organic polymer blend prepared by melting the metal with the polymer, the metal having a melting point within the softening to molten range of the polymer wherein the metal is processed with polymer until the metal is in fibrous form.
Claim 2
Dependent Claim
41 words
Metallized organic polymer blend prepared by melting the metal with the polymer, the metal having a melting point within the softening to molten range of the polymer wherein the metal is processed with polymer until the metal is in fibrous form.
Claim 3
Dependent Claim
31 words
Metallized organic polymer blend according to claim 1 wherein the fibrous metal is in the form of strands of metal which are continuously touching over long distances throughout the polymer matrix.
Claim 4
Dependent Claim
40 words
A process of preparing a metallized plastic blend comprising incorporating a molten metal in an organic polymer at a temperature within the softening to molten range of the polymer and continuing the incorporation until the metal is in fibrous form.
Claim 5
Dependent Claim
40 words
A process of preparing a metallized plastic blend comprising incorporating a molten metal in an organic polymer at a temperature within the softening to molten range of the polymer and continuing the incorporation until the metal is in fibrous form.
Claim 6
Dependent Claim
29 words
A process according to claim 3 wherein the blending is continued until the metal is stretched out in the form of strands which are continuously touching over long distances.
