“…By using either physical or chemical modification, compatibility of the polymer matrix and WF in composites is improved. Compatibilizer/coupling agents can also considerably improve the performance of WPC (Klyosov 2007;Kim and Pal 2011). The preferred coupling agents for polyolefin are maleic anhydride-grafted polyethylene (MAPE) or propylene (MAPP).…”

The aim of this study was to produce mahogany (Swietenia macrophylla) wood flour filled polypropylene (both recycled and virgin) composites and to determine the effects of maleic anhydride-grafted polypropylene (MAPP) on the interfacial compatibility, density, and other mechanical properties of the resulting composites. Approximately 40 wt% of mahogany wood flour, and 60 wt% of polypropylene, 3 wt% of MAPP, 1.5 wt% of zinc stearate, and 1.5 wt% of wax were used during composite manufacturing. Test specimens were manufactured using extrusion and injection molding processes. The flexural, tensile, impact, and hardness properties of all specimens were determined. Scanning electron microscopy was used to study the morphology and interfacial compatibility of the filler in prepared composites. The test results showed that MAPP use and the filler rates affected the density and mechanical properties of test specimens.

“…Unfortunately, both components are naturally incompatible due to the hydrophilic nature of wood materials and hydrophobic nature of polymers. Compatibility in the composite can be improved by using either physical or chemical modification of the polymer or wood fibre or by using compatibilizers/coupling agents [14]. Compatibilizers/coupling agents can improve the performance of WPC significantly.…”

Millions of tons of plastics are produced and consumed annually and should be recycled in a sustainable way. The effects of different compatibilizers on the properties of wood-mixed waste polymer composites are studied to promote recycling of plastics and to determine the potential of using waste plastics in composites. The effect of different addition levels and blending of compatibilizers is examined as well. The studied properties are microstructure, tensile and flexural properties, impact strength, and water absorption and thickness swelling in immersion. The results show that the addition of the selected compatibilizers improved the properties of wood-mixed waste polymer composites remarkably—all the studied mechanical properties and moisture resistance were improved by 50% or more. The effects depend strongly on the level of addition and the compatibilizer used. Findings show that compatibilization provides a feasible means to recycle waste plastics as feedstock for wood–plastic composites.

“…Minkova et al 17 revealed that SEBS-g-MA had a higher compatibilizing efficiency than SEBS at 2 phr loading, as apparent from an increase of zero shear viscosity ( η ) of LDPE/PA6 blend from 5200 to 5400 Pa·s. Kim and Pal 18 reported that the η of PP/wood fiber (WF) composites was the highest (1585 Pa·s) in the presence of SEBS-g-MA at 10 phr, followed by SEBS (1260 Pa·s), and without compatibilizer (1000 Pa·s). The reactions between WF and the polar compatibilizer were found responsible.…”

Polyamide12 (Nylon12)/natural rubber (NR) blend was prepared by melt mixing in a Brabender mixer using polystyrene/maleated natural rubber (PS/MNR) copolymer as a reactive compatibilizer. The influence of compatibilizer loading (1, 3, 5, 7, and 10 phr), shear rate (10–500 s−1), and temperature (200–220°C) on the flow properties (i.e., shear viscosity ( η), power law index, flow activation energy ( Ea), and extrudate swell) of (Nylon12/NR)/(PS/MNR) blends was investigated. The blends showed pseudoplastic behavior from an evident increase of shear stress and a reduction of η with increasing shear rate. The values of η and Ea of the blends were also found to increase with the compatibilizer loading. It suggests that PS/MNR copolymer functioned properly and enhanced the compatibility and interfacial interaction between Nylon12 matrix and NR domains via the formation of amide and succinimide linkages at the interfaces. This reactive compatibilization also caused in a reduction of extrudate swell apparently due to slower elastic recovery of polymer chains.
