COMPOSITION >90% Hazardous Impurities/Residual Monomers One hazardous impurity/residual monomer is present at a level above the concentration cut-off for classification. The impurity is present at a concentration of and may result in sensitisation by skin contact (R43 ≥1% classification). PHYSICAL AND CHEMICAL PROPERTIES Appearance at 20 ºC and 101.3 kPa: Yellow liquid* Property Value Data Source/Justification Freezing Point -41.9 oC Measured Boiling Point Decomposition at ~240 oC at Measured 101.3 kPa Density* 970 1,050 kg/m3 at 20 oC MSDS – Vapour Pressure* 1x10-4 kPa at 20 oC MSDS Water Solubility Measured ≥466.9 g/L Hydrolysis as a Function of pH Not determined No hydrolysable groups present. Partition Coefficient log Kow = 0.99 Measured (n-octanol/water) Adsorption/Desorption log Koc = 1.21 at 25 C Estimated for a representative low molecular weight oligomer using KOCWIN v2.00 (US EPA 2009). Expected to sorb to soil and sludge based on presence of cationic functionality. Dissociation Constant pKa ~10 Based on data from analogous compounds. Flash Point* >100 oC (closed cup) MSDS Autoignition Temperature Not determined Not expected to autoignite under normal conditions based on the flash point. Explosive Properties Not determined There are no chemical groups within the structure that imply explosive properties. Oxidising Properties Not determined There are no chemical groups within the structure that imply oxidative properties. *For imported product containing notified polymer. ≤70% Discussion of Properties For full details of tests on physical and chemical properties, refer to Appendix A.
