Abstract

La presente invencion se relaciona con un método para terminar una polimerizacion en emulsion iniciada por radicales libres utilizando un agentede terminacion que contiene un radical libre de nitroxilo estable o es apto para formar un radical libre de nitroxilo estable in situ. Además deproporcionar una terminacion más eficaz de la polimerizacion, la presente invencion no contiene precursores de nitrosaminas ni es tampoco el agentede terminacion, es fácilmente eliminado durante el procesamientodel látex y los polímeros.
