INDUSTRIAL CHEMICALS (NOTIFICATION AND ASSESSMENT) REGULATIONS 1990 - REG 4A

         (1)   A polymer that has a number average molecular weight that is greater than 1 000, but less than 10 000, is a polymer of low concern for subparagraph (a) (i) of the definition of that term in section 5 of the Act, if the polymer:

                (a)    has less than 10% by mass of molecules with molecular weight that is less than 500; and

               (b)    has less than 25% by mass of molecules with molecular weight that is less than 1 000; and

                (c)    complies with subregulation (2), (3) or (4). 

         (2)   The polymer must consist only of low concern reactive functional groups mentioned in column 2 of Schedule 3. 

         (3)   If the polymer includes moderate concern reactive functional groups mentioned in column 3 of Schedule 3:

                (a)    the groups must have a combined functional group equivalent weight of at least 1 000; and

               (b)    the polymer must include no high concern reactive functional groups mentioned in column 4 of Schedule 3.

         (4)   If the polymer includes high concern reactive functional groups mentioned in column 4 of Schedule 3, the groups must have a combined functional group equivalent weight of at least 5 000.
