EXTRUDIERTE MONOFILEN AUS POLYPHENYLENSULFID ENTHALTENDE KOMPATIBILISIERTE POLYMERMISCHUNGEN UND DAMIT HERGESTELLTE GEWEBE

An extruded monofilament is formed from a compatibilized blend of polyphenylene sulfide and a polyamide resin. The blend is compatibilized by the addition of a compatibilizing resin selected from the group consisting of chemically modified and functionalized polyolefins. Preferably, from about 25 to...

Beschreibung
Zusammenfassung:	An extruded monofilament is formed from a compatibilized blend of polyphenylene sulfide and a polyamide resin. The blend is compatibilized by the addition of a compatibilizing resin selected from the group consisting of chemically modified and functionalized polyolefins. Preferably, from about 25 to about 99 parts by weight of a polyphenylene sulfide resin and from about 75 to 1 parts by weight of at least one polyamide resin, together with from about 0.1 to 10 parts by weight of a compatibilizer are blended and extruded to form the monofilament. The resultant monofilament exhibits improved physical properties as compared to unblended polyphenylene sulfide resins (PPS), as well as uncompatibilized blends of PPS with other materials. The monofilaments prepared from these compatibilized blends are useful as components of industrial fabrics, particularly fabrics such as are used as belts on paper forming machines. The polymer blend and a process for the manufacture of the monofilaments are also provided.
