POLYPROPYLENE COMPOSITE Russian patent published in 2017 - IPC C08L23/14 C08L23/12 C08K7/04 

FIELD: chemistry.

SUBSTANCE: composition comprises a random copolymer of polypropylene and ethylene and/or C_4-C₈-olefin α(PP-RACO), fiber (F) and polar modified polypropylene as an adhesion promoter (AP). The polymer contained in the reinforced composition forms a continuous phase which is a matrix of composition, reinforced by fibers. In addition, the propylene random copolymer has a melt flow rate MFR₂ (230°C) measured according to ISO 1133, at least 5 g/10 minutes, and the fibers (F) are selected from the group consisting of glass fibers, metal fibers, mineral fibers, ceramic fibers and graphite fibers.

EFFECT: composition provides a good balance of mechanical properties such as flexural modulus, impact strength and elongation, and excellent fluidity.
