Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
44 words
An oriented polyamide monofilament having uniformly coated thereon about 2-10 percent, by weight of the monofilament, of a copolymer of vinylidene chloride and at least one ethylenically unsaturated monomer copolymerizable therewith, the copolymer containing at least about 75% by weight of vinylidene chloride units.
Claim 2
Dependent Claim
44 words
An oriented polyamide monofilament having uniformly coated thereon about 2-10 percent, by weight of the monofilament, of a copolymer of vinylidene chloride and at least one ethylenically unsaturated monomer copolymerizable therewith, the copolymer containing at least about 75% by weight of vinylidene chloride units.
Claim 3
Dependent Claim
16 words
A polyamide monofilament of claim 1 wherein the vinylidene chloride coating comprises about 4-6 weight percent.
Claim 4
Dependent Claim
18 words
A polyamide monofilament of claim 1 copolymer is a terpolymer of vinylidene chloride, methyl methacrylate and itaconic acid.
Claim 5
Dependent Claim
19 words
