摘要

正

The non-isothermal crystallization kinetics of poly（ethylene terephthalate）（PET） modified by poly （ethlene glycol）（PEG） were determined by DSC. The dual linear regression method was used to evaluate the relationship between the reciprocal of t 1/2 （ the half life of crystallization） and the appropriate temperature variable. The parameters such as the activation energy （Ed） for transport

the equilibrium melting temperature （T

）

the nucleation parameter （ψ）

themaximum crystallization temperature (T

max

)

and the kinetic crystallizability （G） for the copolyesters were obtained. The influence of the PEG content in PET chains on the parameters characterizing crystallization kinetics and crystallization thermodynamics was discussed.
