Polymeric polyols

1 Scope

This standard specifies the designation, requirements, test methods, inspection rules, marking, packaging, transportation and storage of polymeric polyols.

This standard is applicable to polymeric polyols synthesized from polyether polyols, styrene, acrylonitrile, etc.

3 Rules for designation

3.1 Designation of polymeric polyols

The designation of polymeric polyols consists of fixed name and characteristic items, with the fixed name as polymeric polyols ("POP" for short). The characteristic item group consists of two character groups: character group 1, representing the hydroxyl number of the basic polyether polyol, which is expressed by two digits, and character group 2, representing the mass fraction of styrene and acrylonitrile in polymeric polyols, which is also expressed by two digits. The designation pattern of polymeric polyols is shown in Table 1.
