| Abstract: | A study on kinetics of solid state ploycondensation of two kinds of copolyesters copolymers of polyethylene terephthalate is carried out.One copolycondensation monomer is isophthalic acid and the other adipic acid.The kinetics are conformarity with second-order reaction equation,the reaction rate constant value(k) and reaction energy(Ea) are obtained.It is shown,that the reaction rate on solid state polycondensation of copolyesters is obviously faster than pure polyester(PET). |
