Phenylene sulfide/biphenylene sulfide copolymer pipe. |
摘要 |
<p>Disclosed herein is an improved pipe comprised of phenylene sulfide/biphenylene sulfide copolymers. The improved pipe has greater flexibility and ductility than pipe produced from normal PPS resin. Also disclosed is a method of producing such pipe by preparing a phenylene sulfide/biphenylene sulfide copolymer and forming the copolymer into essentially amorphous pipe by extrusion followed by rapid and uniform quench to avoid pipe crystallization. Also disclosed is a method wherein such amorphous pipe is oriented by subsequent die extrusion. <IMAGE></p> |
