Abstract
A process for the manufacture of polytrimethylene ether glycol comprising polycondensing a 1,3-propanediol reactant selected from the group consisting of 1,3-propanediol and/or oligomers or prepolymers of 1,3-propanediol having a degree of polymerization of 2-9 and mixtures thereof using a polycondensatio n catalyst to form a polytrimethylene ether glycol at less than one atmosphere pressure. In addition, polytrimethylene ether glycol has a number average molecular weight greater than 1,500, an APHA color of less than 120, an unsaturation of less than 20 meq/kg, and a content of cyclic ether oligomers of less than 2 %.
