ABSTRACT OF THE DISCLOSURE 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 such that either the stem or branch thereof is a polyorganosiloxane and the other is an acrylic polymer constituted of a monomer selected from the group consisting of acrylic acid, methacrylic acid, and esters of acrylic and methacrylic acids. |
