Polyethyleneimine, M.W. 50,000 - 100,000 50% in aqueous solution, viscous solution

Supplier: MP Biomedicals
Description: Polyethylenimine is a branched chain polymer having a ratio of 1:2:1 of primary:secondary:tertiary amines with a branching site every 3 to 3.5 nitrogen atoms and a base structure of (CH₂CH₂NH)x. The nitrogen atoms must be protonated to achieve cationic charge, so the cationic charge density is pH dependent.
