Abstract
Abstract A binary copolymer having a melt index of 16g/10 min or less measured at a temperature of 190*C under a load of 2,160 g consisting of (a) ethylene; and (b) a comonomer selected from glycidyl methacrylate, glycidyl acrylate and allyl-glycidyl ether; or a mixed composition comprising (a'') as a first component, one or more of the above mentioned binary copolymers; and (b'') as a second component, one or more other copolymers consisting of (a'''') ethylene; and (b'''') a comonomer selected from an alkyl acrylate, an alkyl methacrylate and vinyl acetate, is coated on one or both surfaces of a metal tape to make a laminate tape. The laminate tape is used for preparing a laminate sheathed cable. The laminating resin may contain an antioxidant.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A laminated tape composed of a metal tape, said metal tape being characterized in that a mixed copolymer composition consisting of (a'') as a first component, one or more of a copolymer having a melt index of 16 g/min or less measured at 190*C under a load of 2,160 g comprising (a) ethylene and (b) a comonomer selected from the group consisting of glycidyl methacrylate, glycidyl acrylate and allyl-glycidyl ether; and (b'') as a second component, one or more of a copolymer comprising (a'''') ethylene and (b'''') a comonomer selected from the group consisting of an alkyl acrylate, an alkyl methacrylate and vinyl acetate, is coated on one or both surfaces of the metal tape.
Claim 2
Dependent Claim
33 words
A laminate tape as claimed in claim 1 wherein an anti-oxidant is added to the copolymer to be laminated on the metal tape in an amount of 100-10,000 ppm, based on the copolymer.
Claim 3
Dependent Claim
35 words
A laminate tape as claimed in claim 2 wherein an anti-oxidant is added to the mixed copolymer composition to be laminated on the metal tape in an amount of 100-10,000 ppm, based on the copolymer.
Claim 4
Dependent Claim
20 words
A laminate tape as claimed in claim 2 wherein the concentration of the second component is 5-95 percent by weight.
Claim 5
Dependent Claim
92 words
A laminate sheathed cable characterized in that a laminate tape composed of a metal tape and a copolymer coated on one or both surfaces of the metal tape, the copolymer having a melt index of 16 g/10 min or less measured at 190*C under a load of 2, 160 g and consisting of (a) ethylene and (b) a comonomer selected from the group consisting of glycidyl methacrylate, glycidyl acrylate and allyl-glycidyl ether, is formed on a cable core in the form of a tube and both ends of said tape are united.
Claim 6
Dependent Claim
139 words
A laminate sheathed cable characterized in that a laminate tape composed of a metal tape and a mixed resin composition coated on one or both surfaces of the metal tape, the mixed resin composition consisting of (a'') as a first component, one or more of a copolymer having a melt index of 16 g/10 min or less measured at 190*C under a load of 2,160 g and consisting of (a) ethylene and (b) a comonomer selected from glycidyl methacrylate, glycidyl acrylate and allyl-glycidyl ether and (b'') as a second component, one or more of a copolymer consisting of (a'''') ethylene and (b'''') a comonomer selected from the group consisting of an alkyl acrylate, an alkyl methacrylate and vinyl acetate, is formed on a cable core in the form of a tube, and both ends of the tape are united.
Claim 7
Dependent Claim
34 words
A laminate sheathed cable as claimed in claim 6 wherein an antioxidant is added to the copolymer to be laminated on the metal tape in an amount of 100-10,000 ppm, based on the copolymer.
