Polymers Exemption Guidance Manual

Polymer Exemption Guidance Manual, EPA 744-B-97-001, 36, question 1 (June 1997), available at http //www.epa.gov/oppt/newchems/pubs/polyguid.pdf [hereinafter Polymer Exemption Guidance Manual]. 

In addition to the six elements listed above, only certain other elements are permitted either as counterions or as an integral part of the polymer. These additional elements are as follows fluorine, chlorine, bromine and iodine (F. Cl. Br and 1) when covalently bonded to carbon, and the monatomic counterions chloride, bromide, and iodide (Cl-. Br- and I-). Polymer Exemption Guidance Manual. 9. 

See Chapter 3, The Inventory. Note that the polymer exemption for polyesters does not disregard starting materials that are charged or present at less than two percent. Polymer Exemption Guidance Manual, 43 (question 37). 

The EPA noted that there are several classes of organic polymers that are included in the polymer exemption because they only have these low-concern reactive functional groups. The Polymer Exemption Guidance Manual says ... 

Hie low-concem functional groups are not taken into account in calculating the reactive group equivalent weight. See Polymer Exemption Guidance Manual, 12. 

Examples of analytical methods are given in the regulations and in the Polymer Exemption Guidance Manual.
