POLYPROPYLENE PLASTIC MATERIAL OBTAINED VIA BLOW EXTRUSION, PROPYLENE FIBRE AND NONWOVEN MATERIAL FROM SAID FIBRE, AS WELL AS PRODUCTION METHODS THEREOF

摘要

FIELD: chemistry.;SUBSTANCE: described is a propylene homopolymer capable of blow extrusion from molten mass. Melt flow rate ranges from 300 to 2500 g/10 minutes at 230°C. Polydispersion index ranges from 1.3 to 2.9. Melting point is equal to 160°C. The invention also describes a method of producing fibre from a propylene homopolymer, involving reaction of a metallocene compound (I), an optional organoaluminium compound and a propylene monomer The invention also describes fibre, nonwoven material and multilayer nonwoven material from the propylene homopolymer.;EFFECT: obtaining a polymer with high melt flow rate and narrow molecular weight distribution, high melting point and low content of by-products in the melt.;12 cl, 5 dwg, 4 tbl, 6 ex
