DESCRIPTION
BS 2782-7:Method 732F:1991
This standard BS 2782-7:Method 732F:1991 Methods of testing plastics. Rheological properties is classified in these ICS categories:
- 83.080.10 Thermosetting materials
This part of ISO 1628 specifies the conditions to be used for the determination of the viscosity number of methyl methacrylate polymer moulding and extrusion materials in dilute solution.
It applies to methyl methacrylate (MMA) homopolymers and copolymers, and mixtures of the two with a minimum of 80 % (m/m) of MMA and up to 20 % (m/m) of other monomers, with and without additives, as defined in ISO 8257-1.
NOTE The dilute-solution viscosity of polymers can be also expressed as a limiting viscosity number [η] (see Annex B).
Method for determination in dilute solution.
