SUMMARY OF ASSESSMENT: 

solid (P) with mp = unk "C (P); 

S is dispersible at 20 "C (P); 

vp c 1.OE-6 mm Hg or torr at 25 "C (P); 

bp >400 "C (P); 

H < 1.OE-8 (P); 

log Koc > 4.5 (P); 

log fish BCF = 0.50 (P) ; 

POTW removal = 90 to 99% via sorption; 

time for complete ultimate aerobic biodegradation > months: 

sorption to soils and sediments-= very strong; 

this polymer (1) will be persistent in the environment, (2) will 

not degrade, and (3) will not release a perfluorinatedhexyl 

monomer of any kind via degradation in the environment; 

PBT Potential: P331T1 

*CEB FATE: 

HEALTH: 

FATE : -- 

migration to ground water .-= negligible; 

Absorption nil all routes based on physical/chemical 

properties; - 

- -- rconcern for lung toxicity if inhaled due to cationic bindihg with 

membranes and water-proofing of membranes by the perF a4kyls;- 

low-moderate Goncern. 

*CEB HEALTH: Exposures to humans: inhalation; 

* 

ECOTOX: Predicted (P) and measured (M) toxicity values in mg/L 

(ppm) are: 

fish 96-h LC50 = 1.9 P 

daphnid 48-h LC50 = 2.7 P 

green algal 96-h EC50 = 0.420 P 

fish chronic value = 0.110 P ,~ 

daphnid ChV = 0.200 P 

algal ChV = 0.110 P 

Predictions are based on SARs for polycationic polymers with 2.0% 

amine-N; SAR chemical class = polymer-cationic-2.0% amine-PT; 

effective concentrations based on 100% active ingredients and 

with 10% <lo00 and 0% ~500; pH7; S = dispersible; -
