Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
51 words
Glass fibers in contact with the residue produced by removing water from a composition consisting essentially of a vinylpyridine-butadiene-styrene terpolymer, a polybutadiene homopolymer latex, a wax emulsion and a resorcinol-formaldehyde resin, with the polybutadiene homopolymer being present in an amount within the range from aboout 30 to about 80 weight percent.
Claim 2
Dependent Claim
51 words
Glass fibers in contact with the residue produced by removing water from a composition consisting essentially of a vinylpyridine-butadiene-styrene terpolymer, a polybutadiene homopolymer latex, a wax emulsion and a resorcinol-formaldehyde resin, with the polybutadiene homopolymer being present in an amount within the range from aboout 30 to about 80 weight percent.
Claim 3
Dependent Claim
29 words
Glass fibers of claim 1 in which said vinylpyridine terpolymer is comprised of about 70 weight percent butadiene, about 15 weight percent styrene and about 15 weight percent vinylpyridine.
Claim 4
Dependent Claim
24 words
Glass fibers of claim 1 in which said wax emulsion contains about 75 weight percent paraffin wax and about 25 weight percent microcrystalline wax.
Claim 5
Dependent Claim
91 words
Glass fibers of claim 1 in which said vinylpyridine terpolymer is contained in said residue in an amount within the range of from about 10 to about 60 weight percent, said polybutadiene latex is contained in an amount within the range of from about 30 to about 80 weight percent, said wax emulsion is contained in an amount within the range of from about 4 to about 6 weight percent and said resorcinol-formaldehyde resin is contained in an amount within the range of from about 3 to about 4 weight percent.
Claim 6
Dependent Claim
17 words
Glass fibers of claim 1 in which said fiber is accumulated in the form of a package.
Claim 7
Dependent Claim
12 words

Claim 8
Dependent Claim
61 words
A plurality of glass fibers and an impregnant for the glass fibers, said impregnant being a residue formed by removing water from a composition consisting essentially of a vinylpyridine-butadiene-styrene terpolymer, a polybutadiene homopolymer latex, a wax emulsion and a resorcinol-formaldehyde resin, with the polybutadiene homopolymer being present in an amount within the range from about 30 to about 80 weight percent.
Claim 9
Dependent Claim
61 words
A plurality of glass fibers and an impregnant for the glass fibers, said impregnant being a residue formed by removing water from a composition consisting essentially of a vinylpyridine-butadiene-styrene terpolymer, a polybutadiene homopolymer latex, a wax emulsion and a resorcinol-formaldehyde resin, with the polybutadiene homopolymer being present in an amount within the range from about 30 to about 80 weight percent.
Claim 10
Dependent Claim
23 words
Glass fibers as defined in claim 7 wherein the wax emulsion contains 75% by weight paraffin wax and 25% by weight microcrystalline wax.
