Abstract: A process for preparing high melt strength propylene polymers is provided. The process comprises: blending base propylene polymers with 0.1 to 1% w/w of polyfunctional acrylate monomer, in the presence of 10 to 50 ppm organic peroxide and 0.2 to 20% w/w of an additive such as stabilizer, acid neutralizer, antioxidants or lubricants. The high strength modified propylene polymers obtained have 30 to 60% of increased melt strength than that of the base propylene polymers.

Abstract: A process of modifying propylene polymers via melt grafting of polyfunctional monomer (PFMs) 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.
