POLYPROPYLENE COMPOSITION, REINFORCED BY FIBERS WITH HIGH FLUIDITY Russian patent published in 2016 - IPC C08L23/10 C08L23/12 C08L23/16 C08K7/02 

FIELD: technological processes.

SUBSTANCE: invention relates to a composition, reinforced by fibers, and articles made from it. Composition contains a heterophase copolymer of propylene, propylene homopolymer and/or copolymer of propylene and fibre with average diameter 12.0 mcm or less and aspect ratio of 150 to 450. Heterophase propylene copolymer contains polypropylene matrix (M-PP), in which dispersed elastomeric copolymer (E1) containing units obtained from propylene and ethylene and/or with C₄-C₂₀ α-olefin. Composition reinforced with fibres, has melt flow rate MFR₂ (230 C), measured according to ISO 1133, at least 10 g/10 min.

EFFECT: composition reinforced with fibres, has melt flow rate MFR₂ (230 C), measured according to ISO 1133, at least 10 g/10 min and has good balance of mechanical properties, such as modulus of elasticity in flexure, impact strength and elongation.
