Synthesis of core–shell polyurethane–ureananoparticles containing 4,4′-methylenedi-p-phenyl diisocyanate and isophorone diisocyanate by self-assembled neutralization emulsification

Abstract

Polyurethane–urea nanoparticles containing 4,4′-methylenedi-p-phenyl diisocyanate and isophorone diisocyanate were synthesized by utilizing self-assembled neutralization emulsification and their particle morphology could be controlled.
