Abstract
The invention relates to a process for preparing ABS polyblends by grafting large diene rubber particles in aqueous latices in the presence of oligomeric surfactants providing large grafted diene rubber particles in latices that are stable and essentially free of coagulum. The ABS polyblends recovered from such latices are free of hard spots and have superior toughness.
