4I Polymer of low concern—other characteristics (Act s 5)

(1A) For the purposes of paragraph (f) of the definition of polymer of low concern in subsection 5(1) of the Act, the characteristics set out in this regulation are prescribed. (1) A polymer must contain as an integral part of its composition at least 2 of the following atomic elements: (a) carbon; (b) hydrogen; (c) nitrogen; (d) oxygen; (e) silicon; (f) sulphur. (2) A polymer must not contain as an integral part of its composition (except as impurities) an atomic element other than the following: (a) aluminium as the monatomic counterion Al3+; (b) bromine as the monatomic counterion Br‑; (c) bromine covalently bound to carbon; (d) calcium as the monatomic counterion Ca2+; (e) carbon; (f) chlorine as the monatomic counterion Cl‑; (g) chlorine covalently bound to carbon; (h) fluorine covalently bound to carbon; (i) hydrogen; (j) iodine as the monatomic counterion I‑; (k) iodine covalently bound to carbon; (l) magnesium as the monatomic counterion Mg2+; (m) nitrogen; (n) oxygen; (o) potassium as the monatomic counterion K+; (p) silicon; (q) sodium as the monatomic counterion Na+; (r) sulphur; (s) less than 0.2% (by weight) of any combination of the following atomic elements: (i) boron; (ii) copper; (iii) iron; (iv) lithium; (v) manganese; (vi) nickel; (vii) phosphorus; (viii) tin; (ix) titanium; (x) zinc; (xi) zirconium. (3) A polymer that is capable of absorbing its own weight in water must not have a number average molecular weight that is 10 000 or greater. (4) A polymer must not contain as an integral part of its composition (except as an impurity) a chain (whether branched or linear) of fully fluorinated carbon atoms, at least one end of which is terminated by a perfluoromethyl (CF3) group.
