Diol Composition And Polyester
Abstract: Provided is a polyester with an excellent color tone and improved molding stability and mechanical properties. This improvement is achieved by controlling the electrical conductivity of the diol composition which is a raw material for the polyester to be between 0.6 mS/m and 30 mS/m and preferably by controlling the pH of the diol composition to be between 5 and 7.5 thereby reducing the heating weight loss ratio of the polyester.
