8 . The method of claim 7 wherein the polymerized oil is obtained by oxidizing said unsaturated oil or mixture of oils.
9 . The method of claim 8 wherein the sulfated or sulfonated oil is a sulfated or sulfonated vegetable oil and the sulfated or sulfonated vegetable oil is present in an amount to provide a weight ratio of the polymerized oil to the sulfated or sulfonated vegetable oil in the range of 10:90 to 95:5.
10 . A method for preparing a glass fiber product comprising the steps of:
contacting hot glass fibers with an adhesive binder comprising an aqueous dispersion of a thermosetting resin, a catalyst and the dust control agent of claim 1;
forming the glass fibers contacted with the adhesive binder into a non-woven mat, and
heating the mat to cure the adhesive binder.
11 . The method of claim 10 wherein the polymerized oil is obtained by polymerizing an unsaturated oil selected from the group consisting of linseed oil, castor oil, tung oil, soybean oil, cottonseed oil, olive oil, canola oil, corn oil, sunflower seed oil, coconut oil, safflower oil, tall oil, palm oil and mixtures thereof.
12 . The method of claim 11 wherein the polymerized oil is obtained by oxidizing said unsaturated oil or mixture of oils.
13 . The method of claim 12 wherein the sulfated or sulfonated oil is a sulfated or sulfonated vegetable oil and the sulfated or sulfonated vegetable oil is present in an amount to provide a weight ratio of the polymerized oil to the sulfated or sulfonated vegetable oil in the range of 10:90 to 95:5.
14 . A composition suitable for preparing a dust control agent comprising a blend of a polymerized oil and a sulfated or sulfonated oil dispersing agent in an amount to provide a weight ratio of the polymerized oil to the sulfated or sulfonated vegetable oil in the range of 1:99 to 99:1.
15 . The composition of claim 14 wherein the polymerized oil is obtained by polymerizing an unsaturated oil selected from the group consisting of linseed oil, castor oil, tung oil, soybean oil, cottonseed oil, olive oil, canola oil, corn oil, sunflower seed oil, coconut oil, safflower oil, tall oil, palm oil and mixtures thereof.
