Abstract
Se da a conocer un procedimiento para utilizar eficientemente el ácido fosforoso, o una sal del mismo, como un agente de transferencia de cadena en la polimerizacion de monomeros, particularmente monomeros insaturados del ácido carboxíloco, donde la polimerizacion se lleva acabo en un nivel de solidos en procesos de al menos el 40 por ciento y en un nivel de neutralizacion en proceso de al menos el 30%, para producir polímeros terminados en fosfanato, solubles en agua, de bajo peso molecular.
