A copolyester hot-melt adhesive was prepared by transesterification, esterificcation and polycondensation from dimethylterephthalate(DMT), dicarboxylic acid and dihydric alcohol. The influences of nucleating agents and crystallizing promoter on its crystallization kinetics was studied by measurement of depolarized light intensity with time. It was found that the complex additives composed of inorganic nucleating agent, organic agents and crystallization promoter could significantly accelerate the crystallization process of the copolyester due to the reduction of the activation energies of crystal nucleation and crystal growth.
