Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
65 words
A substantially chrome-free aqueous sizing composition for glass fiber gun roving which comprises (A) a mixture of emulsified film-forming polymers comprising a polymer of vinyl acetate and ethylene, a polymer of vinyl acetate and an epoxy-functional vinyl monomer, and an unsaturated polyester resin; (B) titanium acetyl acetonate; (C) a silylated polyamino-polyamide hydrochloride or hydrolysate thereof; (D) a cationic lubricant; and (E) 3-methacryloxypropyltrimethoxysilane or hydrolysate thereof.
Claim 2
Dependent Claim
65 words
A substantially chrome-free aqueous sizing composition for glass fiber gun roving which comprises (A) a mixture of emulsified film-forming polymers comprising a polymer of vinyl acetate and ethylene, a polymer of vinyl acetate and an epoxy-functional vinyl monomer, and an unsaturated polyester resin; (B) titanium acetyl acetonate; (C) a silylated polyamino-polyamide hydrochloride or hydrolysate thereof; (D) a cationic lubricant; and (E) 3-methacryloxypropyltrimethoxysilane or hydrolysate thereof.
Claim 3
Dependent Claim
90 words
An aqueous composition according to claim 1 wherein the proportions by weight of the components relative to the total weight of the aqueous composition, are about: (A) 1 to 5% of said emulsified polymer of vinylacetate and ethylene, 1 to 5% of said emulsified epoxy-functional vinyl monomer, and 0.5 to 1.5% of said emulsified polyester resin; (B) 0.5 to 1.5% of said titanium acetyl acetonate; (C) 0.01 to 0.2% of said silylated polyamide hydrochloride; (D) 0.005 to 0.1% of said cationic lubricant; and (E) 0.005 to 0.1% of said silane.
Claim 4
Dependent Claim
52 words
An aqueous composition according to claim 2 wherein said epoxy-functional vinyl monomer is glycidyl acrylate or methacrylate, said unsaturated polyester resin comprises a minor proportion by weight at an unsaturated plasticizer latently reactive therewith, and said cationic lubricant is a weak acid salt of a partial fatty acid amide of a polyamine.
