Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
Glass fibers having thereon the dried residue of a sizing composition comprising: a water solubilized, condensation, cross-linkable, first unsaturated polyester resin, said polyester resin substantially insoluble in aromatic solvents when crosslinked; a second unsaturated water dispersible and insoluble polyester resin, said second polyester resin being insoluble in said first polyester resin in a water solution and said second polyester resin preventing the migration of said sizing composition; a plasticizer; a first silane coupling agent to promote adhesion between said glass fibers and said resin matrix; a second silane coupling agent to control the wetting of said glass fibers by said first silane coupling agent; a thermoplastic polymer being of sufficiently low molecular weight to impart pressure sensitive adhesive characteristics to said sizing composition; and a major amount of water.
Claim 2
Dependent Claim
129 words
Glass fibers having thereon the dried residue of a sizing composition comprising: a water solubilized, condensation, cross-linkable, first unsaturated polyester resin, said polyester resin substantially insoluble in aromatic solvents when crosslinked; a second unsaturated water dispersible and insoluble polyester resin, said second polyester resin being insoluble in said first polyester resin in a water solution and said second polyester resin preventing the migration of said sizing composition; a plasticizer; a first silane coupling agent to promote adhesion between said glass fibers and said resin matrix; a second silane coupling agent to control the wetting of said glass fibers by said first silane coupling agent; a thermoplastic polymer being of sufficiently low molecular weight to impart pressure sensitive adhesive characteristics to said sizing composition; and a major amount of water.
Claim 3
Dependent Claim
172 words
Glass fibers having thereon the dried residue of a sizing composition comprising 1 to 10 percent by weight of a water solubilized condensation, cross-linkable, first unsaturated polyester resin, said polyester resin substantially insoluble in aromatic solvents when crosslinked; 2 to 10 percent by weight of a second unsaturated water dispersible and insoluble polyester resin, said second polyester resin being insoluble in said first polyester resin in a water solution and said second polyester resin preventing migration of said sizing composition; 2 to 16 percent by weight of a plasticizer; 0.1 to 1.5 percent by weight of a first silane coupling agent to promote adhesion between said fibers and said resin matrix; 0.1 to 1.5 percent by weight of a second silane coupling agent to control the wetting of said glass fibers by said first silane coupling agent; 1to 6 percent by weight of a thermoplastic polymer being of sufficiently low molecular weight to impart pressure sensitive adhesive characteristics to said sizing composition; and a minimum of 80 percent by weight of water.
Claim 4
Dependent Claim
172 words
Glass fibers having thereon the dried residue of a sizing composition comprising 1 to 10 percent by weight of a water solubilized condensation, cross-linkable, first unsaturated polyester resin, said polyester resin substantially insoluble in aromatic solvents when crosslinked; 2 to 10 percent by weight of a second unsaturated water dispersible and insoluble polyester resin, said second polyester resin being insoluble in said first polyester resin in a water solution and said second polyester resin preventing migration of said sizing composition; 2 to 16 percent by weight of a plasticizer; 0.1 to 1.5 percent by weight of a first silane coupling agent to promote adhesion between said fibers and said resin matrix; 0.1 to 1.5 percent by weight of a second silane coupling agent to control the wetting of said glass fibers by said first silane coupling agent; 1to 6 percent by weight of a thermoplastic polymer being of sufficiently low molecular weight to impart pressure sensitive adhesive characteristics to said sizing composition; and a minimum of 80 percent by weight of water.
Claim 5
Dependent Claim
22 words
The glass fibers of claim 1 wherein the sizing composition producing the dried residue is at a pH of less than 7.
