Book excerpt: The principal objective of this thesis is to elucidate how the rubber phase produced in the copolymerisation step is distributed inside growing particles of high impact polypropylene, and how the amount of rubber incorporated in the original polypropylene matrix influences the overall morphology and mechanical properties of the final product. To this end, polymer was made under different conditions, and the products were characterised and analysed in order to attempt to understand how the morphology of the isotactic polypropylene matrix changes during particle growth, how rubber flows in the porous network, and how the EPR arrives at, and pools on the surface of the particle. All of these phenomena are obviously dependent on each other, which complicates the problem. A representation which incorporates the rheological properties of the copolymer combined with the structure of the homopolymer polypropylene matrix is probably a more realistic approach to take.
