Title
High impact polypropylene: Influence of copolymerization conditions on powder and polymer properties
Conference Dates
May 20-25, 2018
Abstract
Isotactic Polypropylene (iPP) is more rigid than polyethylene (PE) but less tough, especially at lower temperatures. Incorporation of an elastomer of ethylene-propylene helps with this issue. Industrially this is typically done in two reaction steps. Initially iPP particles are polymerized, and afterwads a dispersed elastomeric phase is copolymerized in the still-reactive homopolymer matrix, always in the gas phase.
