An autohesive polymer material that includes: at least one polymer having at least two terminal silyl groups of the Formula (1) given by:

Si(R.sup.1).sub.a(R.sup.2).sub.b(1).

Each of the radicals R.sup.1 comprises an alkyl, alkenyl or aryl group or a hydrogen atom. Each of the radicals R.sup.2 comprises a group that can be eliminated with water, b is 1, 2 or 3, and a is 3b. The polymer material further includes at least one condensation catalyst. Further, the polymer material is chemically precrosslinked and further crosslinkable with moisture. In addition, the polymer material is configured for use as a layer body that can be applied to a substrate. The polymer material of this kind can also be used for producing permanent bonds.

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).
