چکیده
|
In this study, we applied multimodal polymerization in the slurry phase to synthesize polyethylene resin with improved properties than bimodal and commercial samples. synthesized resins characterized by various methods involve melt flow index (mfi), flow rate ratio(frr), differential scanning calorimetry(dsc), stain hardening mudolous(shm), and rheometeric mechanical spectrometer(rms). the result shows that the multimodal sample has better processability, sagging resistance,and slow crack growth by comparing rheological behavior and shm to bimodal and commercial samples.
