Polyethylenimine HCl MAX, Linear, Mw 40,000 (PEI MAX 40000)

Description

Linear polyethylenimine HCl MAX, Mw 40,000 (PEI MAX 40000) is a fully hydrolyzed (deacylated), highly water soluble hydrochloride salt of PEI 25000. PEI MAX 40000 contains a longer contiguous ethyleneimine segments resulting in increase in protonable nitrogens than PEI 25000

PEI MAX 40000 is supplied as a hydrochloride salt for ease of handling and high water solubility. PEI MAX 40000 can be converted into the linear free amine (PEI ~22000) form by neutralization with base.

 

CAS#: 26338-45-4, 9002-98-6, 26913-06-4

Molecular Weight: 40,000 (~22,000 free base)

Soluble In: Cold and room temperature water
Insoluble in: Common organic solvents (ethanol, acetone, tetrahydrofuran)

 

Appearance:White to off-white free flowing solid
