Abstract: A binder composition and method for using same in sizing compositions for treating glass fibers is provided. The binder composition is an aqueous emulsion containing isotactic carboxylated polypropylene along with amorphous carboxylated polypropylene, base, and surfactant. The isotactic carboxylated polypropylene is incorporated in the emulsion by a method of co-emulsification of the isotactic and amorphous carboxylated polypropylene in a ratio of 1:1 to 1:4 parts by weight along with the base and surfactant. Water is added to the co-emulsified blend to obtain the emulsion with the desired solids content.

Abstract: Sizing compositions, sized glass fiber strands are used to produce reinforced polymeric materials that have improved UV stability while maintaining good physical properties. The sizing composition, sized glass fiber strands and reinforced polymeric materials having sized glass fiber strands involve the use of materials in the sizing composition, such as polyurethane polymers, ureidofunctional silanes, aminofunctional silanes, lubricants and processing aids.One particular aspect of the present invention has materials associated with the sizing composition, sized glass fiber strands and reinforced polymers such as polyamides, polyethyleneterephthlate, polybutyleneterephthlate, polystyrenics, thermosetting esters, and chemically coupled polypropylene that are thermoplastic, aliphatic, polyurethane polymer dispersions, ureidofunctional silane, gamma-aminopropyltriethoxysilane, a lubricant modified gamma-aminopropyltriethoxysilane, dibutyphthalate, polyalkylene polyol lubricant, and a polyester film former.

Abstract: Continuous glass fiber with a polyolefin compatible sizing composed of a coupling agent, a stabilizer, a lubricant, a non-crosslinking film forming polymer, softening agent and surfactant are disclosed for utilization in polyolefin polymer reinforcement. The article formed and formation method for fiber combination with a polyolefin polymer are also disclosed.

Abstract: A method of improving the surface characteristics of a formed article of magnesium oxychloride or magnesium oxysulfate cement is shown in which molded articles of magnesium oxychloride or magnesium oxysulfate are treated with water at temperatures of 90.degree. F. to 212.degree. F. (32.2.degree. C. to 100.degree. C.) for periods of 1 to 30 minutes or longer to prevent the formed article from efflorescing.
