摘要
对两种共聚酯作了固相聚合动力学研究，其动力学符合二级反应方程。求出了反应速度常数ｋ和活化能Ｅｎ。结果表明，共聚酯固相聚合反应速度明显快于纯聚酯。
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).
