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.
