Producing polypropylene composition in e.g. bumpers, by adsorbing polymerization catalyst on halloysite nanotubes, saturating solution of propylene monomer, mixing nanotube with saturated solution, and polymerizing mixed propylene monomer
Producing a polypropylene composition comprises adsorbing a polymerization catalyst on halloysite nanotubes, saturating a solution of a propylene monomer, mixing the halloysite nanotube with the saturated solution of propylene monomer, and polymerizing mixed propylene monomer for obtaining a polypropylene composition. An independent claim is included for a polypropylene composition obtained by the method, where the amount of the halloysite nanotube is 4-8 mass%.
