Plastics - Determination of viscosity number of PVC resins in dilute solution
inactive, Most Current
| Organization: | NEN |
| Publication Date: | 1 June 1975 |
| Status: | inactive |
| ICS Code (Thermoplastic materials): | 83.080.20 |
scope:
This International Standard specifies a method for determining the viscosity number of dilute solutions, in cyclohexanone, of PVC resins or copolymers in which the principal constituent is vinyl chloride. The viscosity number thus determined gives an approximation of the molecular mass of the PVC resin.
