A mixture of fumaric acid (0.01 mol), itaconic acid (0.01 mol), and 1,4-butanediol (0.02 mol) with 0.1 mmol of TTiPO as catalyst taken in reaction bath was slowly heated to 160[degrees]C and stood for 2h under dry nitrogen atmosphere and after 2 h the temperature was further increased to 190[degrees]C and kept under vacuum for 1h to remove the traces of water.
