Polyesters

Last update 23 March 2017

A polyester is defined as a chemical substance meeting the definition of polymer in the Act with polymer molecules containing at least two carboxylic acid ester linkages, at least one of which links internal monomer units.

Polyesters manufactured from an approved list of monomers or other reactants are eligible for notification as PLCs, provided they satisfy all other PLC criteria. This provision is independent of the NAMW.

The list of approved monomers and other reactants from which polyester may be made is in the table below.

A number of reactants on this list are not on the Australian Inventory of Chemical Substances (AICS). Therefore, the manufacture of polyesters from these reactants cannot be carried out in Australia without notification to and assessment of the reactants by NICNAS.

On the other hand, polyesters manufactured from these reactants overseas could be imported, as the reactant itself would not be introduced.

Note: Polyesters manufactured from the anhydride of an acid on the polyester list—for example, succinic anhydride (butanedioic acid)—are allowed, provided there are no pendant anhydrides in the polymer.

In summary, certain polyesters will not be eligible for notification as PLCs, including:

  • biodegradable polyesters, which do not meet the degradation criterion
  • water-absorbing polyesters
  • polyesters manufactured from any monomer or other reactant not on the list of allowable reactants, including such a reactant at <2%.
