Abstract
A process for producing a polyester in a stable emulsion state, which comprises thermal polymerization of a bis(.omega.-hydroxyalkyl)terephthalate or an oligomer thereof in the form of finely divided particles dispersed in a silicone oil by using a graft polymer, as a dispersion stabilizer, constructed of both a polysiloxane and an acrylic polymer.
