The effect of hydrophile–lipophile balance of water-soluble poly(ethylene glycol)–poly(lactic acid) diblock copolymers on the stability of microscopic emulsion films and nanoemulsions

The effect of the PEG and PLA block length of amphiphilic water-soluble poly(ethylene glycol)–poly(lactic acid) diblock copolymers on the stability to rupture of microscopic liquid films and nanoemulsions is investigated.
