摘要
A process of modifying propylene polymers via melt grafting of polyfunctional monomer (PFM5) involving pre-initiative step thereby facilitating perfect absorption of PFMs on polymer matrix and initiate their grafting prior to reactive extrusion without using free radical initiators so that branching can be introduced in propylene polymer matrix. The modified propylene polymers showed enhanced shear sensitivity, increase in molecular weight, broadening of molecular weight distribution and strain hardening.
