Abstract
This work reports the effects of different types of Poly (vinyl chloride) grafted with maleic anhydride on the fiber–matrix compatibility in terms of wettability and dynamical properties of composites. The elaborated composites were compounded with alfa fibers and Poly (vinyl chloride) (PVC). The applied treatments were maleic anhydride-Poly (vinyl chloride) copolymer (PVC-g-MA) with three different quantities of MA grafted (PVC-g-MA1, PVC-g-MA2 and PVC-g-MA3). Both DMA and contact angle results indicated that all compatibilizers led to better adhesion and the wetting behavior of PVC/alfa composites. All properties of composites were strongly dependent on the amount of MA-grafts. The performance of PVC-g-MA as a compatibilizer in PVC/alfa composites was evaluated. It was observed that PVC-g-MA3 shows a better compatibilizing effect than the PVC-g-MA1 and PVC-g-MA2. Based on the success of these results, it is reasonable to assume that the PVC-g-MA, for which there was no disclosure found in the literature, can be considered for its suitability as a compatibilizer candidate.
