Research & manufacture of national reference materials-fiber polyester chip;

Error origin and countermeasure on the analysis of acetaldehyde content in bottle grade PET chip;

Process optimization of decreasing mass fraction of ethanal in bottle grade PET chips;

Effect of test condition on bottle grade PET chip intrinsic viscosity results;

Preparation of the antibacterial reagent and antimicrobial polyester chips;

The results show that the melting-point of the copolyester chips,synthesized by the optimal proportion modifiers,p-terephthalic acid(PTA) and ethylene glycol(EG),have performances similar to common polyesters such as thermal behavior,rheological behavior,is about 110℃,which accord with the requirements of t.

Introducing and analysing the functions of the static mixers,putting forward the imple- mentation plan in the polyester chips production.
