Polyethylenimine Linear [9002-98-6]<br />
TSCA (C 2 H 5 N) x<br />
All-secondary amine polymer, unlike branched polyethylenimines which contain<br />
primary, secondary and tertiary amino groups and are liquids at all molecular<br />
weights . Soluble in hot water, cold water at low pH, methanol, and ethanol .<br />
Insoluble in benzene, ethyl ether, acetone, and cold water .<br />
Contains up to 7-8% of poly(2-ethyl-2-oxazoline) .<br />

Polyethylenimine “Max” High Potency Linear PEI [9002-98-6] H6g<br />
A nearly fully hydrolyzed linear polyethylenimine with longer contiguous<br />
ethyleneimine segments . Although N-deacylation reactions are notoriously<br />
difficult, our new linear polyethylenimine material is believed to contain<br />
more than 11% additional free (protonatable) nitrogens than our standard<br />
linear polyethylenimine material . Easy to handle hydrochloride salt form .<br />
Insoluble in common organic solvents (ethanol, acetone, tetrahydrofuran)<br />
Soluble in: cold and room temperature water .<br />

White to off-white free flowing solid TSCA<br />
Molecular Weight: ~2,500 Mw in free base form . Nominal 4,000 Mw in hydrochloride salt form .<br />
