High Molecular Mass Polyethylene Aqueous Latexes by Catalytic Polymerization

Semicrystalline microparticles of high molecular mass polyethylene can be prepared as aqueous dispersions (see picture) by catalytic emulsion polymerization of ethylene with a mini‐emulsified catalyst precursor (D$\rm{\frown}$D=salicylaldimine, L=pyridine). Stable polymer latexes are formed.

Summary:Semicrystalline microparticles of high molecular mass polyethylene can be prepared as aqueous dispersions (see picture) by catalytic emulsion polymerization of ethylene with a mini‐emulsified catalyst precursor (D$\rm{\frown}$D=salicylaldimine, L=pyridine). Stable polymer latexes are formed.
