A sustainable procedure for recycling powdered rubber coming from scrap tires (ground tire rubber [GTR]) is proposed as based on the dispersion in polyketone (PK) matrix, obtained in situ by CO/ethylene copolymerization. Three types of catalysts are used operative in solvents of different polarities. The catalyst productivity and the hybrids morphology are evaluated and optimized to final composites features. The obtained products are characterized by scanning electron microscopy, atomic force microscopy, and solvent extractions in order to investigate the occurrence and the extent of interactions between PK macromolecular chains and the GTR components; and their effects on the final properties were tested by differential scanning calorimetry, thermogravimetric analysis, and rheological measurements. For comparison purpose, a composite with GTR included into the matrix through blending is prepared. The results evidenced the key role exerted by the catalyst that, when operative in apolar solvent (able to swell the rubber phase), provides composites with good interfacial adhesion and breaking up of the particles with beneficial effects on final properties particularly thermal features and processability.

“…A traditional core–shell modifier consists of a crosslinked elastomeric core and a rigid glassy shell. A core–shell rubber, Blendex 338, with a polybutadiene (PB) core and a styrene–acrylonitrile shell, was found to be able to toughen POK very effectively, while the tensile modulus and yield stress of the blends decreased almost linearly with increasing rubber content …”

Polyketone (POK), a new environment‐friendly engineering plastic produced from carbon monoxide (CO), can be used for various applications including packaging, fibers and technical items. Due to its exceptional balance of mechanical properties and high chemical resistance, POK holds great potential to be one of the most promising candidates for high‐performance and multifunctional polymer materials. The introduction of other polymer materials, reinforcing fibers or micro‐ and/or nanofillers into the POK matrix is a powerful method for obtaining new POK‐based materials with specific characteristics and satisfactory improvements in properties. This article summarizes and highlights the recent advances and efforts in research and development in the field of POK blends, POK composites and POK blend‐based composites. The applications of POK materials and outlook are also summarized and discussed. © 2018 Society of Chemical Industry

“…Polyketones (PKs), which are obtained by copolymerization of carbon monoxide and ethylene and/or other α‐olefins, are semicrystalline thermoplastics . The polar ketone groups in the polymer backbone give rise to strong attraction between polymer chains, and hence PKs can be used at high temperatures and are stronger and more rigid than most other engineering plastics; they are referred to as super‐plastic materials. However, as a result of these properties, PK is difficult to dissolve in polar solvents such as ethanol, methanol, and acetone.…”

Few solvents are capable of dissolving polyketones (PKs). 1,1,1,3,3,3-Hexafluoro-2-propanol (hexafluoroisopropanol, HFIP) is a better solvent than trifluoroethanol and m-cresol. When HFIP was evaporated from a PK/HFIP solution, a porous cast-film with a microparticle structure was formed because the isotactic PKs adopted a helical conformation, and convection during evaporation of the high polarity and lowboiling-point HFIP caused aggregation and rolling of the polymer molecules. The addition of plasticizer suppressed particle formation, improving the surface structure and mechanical properties of the film. In particular, the dielectric properties of the film improved significantly. This will enable PKs, which are rigid insulating materials, to be used as dielectric materials, broadening their range of applications.
