Methods of making prepregs are described. The methods include the steps of forming a fiber-containing substrate, and contacting the fiber-containing substrate with a resin mixture. The resin mixture may include polymer particles mixed in a liquid medium, and the polymer particles may be coated on the fiber-containing substrate to form a coated substrate. The liquid medium may be removed from the coated substrate to form the prepreg. The prepregs may be used to make fiber-reinforced articles.

A polyphenylene sulfide resin composition is obtained by mixing a polyphenylene sulfide resin (a), a fluororesin (b) and an organosilane compound (c). When a resin phase-separated structure of a molded product formed from the polyphenylene sulfide resin composition is observed by an electron microscope, the component (a) forms a continuous phase, the component (b) forms a primary dispersed phase having a number-average dispersion diameter of not greater than 1 m, and a secondary dispersed phase of the component (a) is included in the primary dispersed phase of the component (b).

Inks, paints, adhesives, and paint strippers may be formulated to include one or more surfactants, from one or more surfactant classes, such as siloxane derivatives of amino acids that have surface-active properties.
