Abstract
Ïã¸ÛÁùºÏ²Ê¿ª½± 307:2003 specifies a method for the determination of the viscosity number (also referred to as reduced viscosity) of dilute solutions of polyamides in certain specified solvents.
The method is applicable to the polyamides designated PA 46, PA 6, PA 66, PA 69, PA 610, PA 612, PA 11, PA 12, PA 6T/66 and PA MXD6 as defined in Ïã¸ÛÁùºÏ²Ê¿ª½± 1874-1, as well as to copolyamides and other polyamides that are soluble in one of the specified solvents under the specified conditions.
The method is not applicable to polyamides produced by anionic polymerization of lactams or produced with crosslinking agents; such polyamides are normally insoluble in the specified solvents.
