Abstract
Abstract Glass fibers are coated with a formulation containing vinyl polymer. 2-10% by weight of an amine compound is added to the vinyl polymer. A typical formulation contains 100 pts. PVC, 6 pts. undecyl benzyl phthalate, 21 pts. tri-o-phosphate, 21 pts. epoxidized tall oil ester, 4 pts. paste aluminum pigment, 2 pts. Sb2O3, a heat stabilizer, a barium-cadmium coupler, an ulta violet stabilizer, and a hydrocarbon thinner. The amines may be vinyl pyrrolidone monomer, propylamine, polyvinyl pyrrolidone acrylamide, aminopolyethylene, polyvinyl pyridine, polyacrylonitrile, hexamethylenediamine, and diphenyl guanidine.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
63 words
In the combination of glass fibers and a vinyl polymer resin composition present as a coating on the glass fiber surfaces, the improvement which comprises mixing the vinyl polymer resin, prior to coating of the glass fibers, with an amine compound in an amount corresponding to 2-10 percent by weight of the vinyl polymer resin, and in which the amine compound is polyethyleneamine.
Claim 2
Independent Claim
70 words
The method of producing glass fibers coated with polyvinyl resin strongly bonded to the glass fiber surfaces comprising the steps of incorporating an amine compound with the polyvinyl resin prior to coating of the resin onto the glass fiber surfaces, in which the amine compound is present in an amount within the range of 2-10 percent by weight of the polyvinyl resin and in which the amine compound is propylamine.
Claim 3
Independent Claim
69 words
