General description

All polyethylene imine polymers are hydrophilic and may contain approx. 30% hydrated water.

Application

Poly(vinyl acetate) is commonly used in biomedical applications. The end group functionality contains a cyanomethyl group; and the RAFT agent diphenylcarbamodithioate which will allow for additional polymerization to generate a diblock copolymer. This RAFT agent is well-suited for vinyl acetates and vinyl benzoate
