Polyolefin granulation method, polyolefin resin, polyolefin fibre, use of polyolefin fibre and cement composites
The present invention relates to a method for producing polyolefin with enhanced polar character by incorporation of surfactants in order to provide polymer resins used for the production of fibres with improved performance that can be used as reinforcing agents in cement composites. More specifically, the polyolefin obtained by polymerization is modified by incorporation of surfactants during the granulation process. Also described is a polymer resin of improved polarity consisting of a polyethylene homopolymer or a polypropylene homopolymer, copolymer or terpolymer, or a blend of two or more of these components, and at least one non-ionic and/or ionic surfactant having a partially polar structure for preparing reinforcing fibres for use in cement composites for manufacturing structural and non-structural components in the field of civil engineering, such as bridge girders, slabs, pavements, large concrete containers, sealing panels, high-performance tiles, inter alia.
