Blends of poly(ethylene-co-vinyl alcohol) (EVOH) with maleic anhydride-grafted-poly(ethylene-octene) (POEg-MAH) were prepared by blending extrusion in order to improve the toughness and flexibility of EVOH. The compatibility behavior of these blends with POE-g-MAH content range from 0 to 25 wt% was studied using mechanical, thermal, infrared, and morphology characterization techniques. The mechanical test results showed that POE-g-MAH can significantly improve the impact toughness of EVOH with a brittletough transition appeared at the POE-g-MAH content of 20 wt%. A huge increase of toughness of the blend was also observed when the POE-g-MAH content was increased to 15 wt%. The thermal analysis of the blends demonstrated that the thermal stability of EVOH is improved with the addition of POE-g-MAH, adding 20 wt% or more POE-g-MAH can effectively decrease the crystallinity of EVOH and greatly improve compatibility between the two components. The existence of esterification between anhydride groups in POE-g-MAH and hydroxyl groups in EVOH in melt processing was confirmed using Fourier transform infrared technique.

Linear low-density polyethylene (LLDPE) was functionalized with succinimide under different experimental conditions like change in time, temperature, and (% weight of succinimide). The FTIR Spectrum inferred that melt grafting of succinimide onto LLDPE followed the 0.50 order of reaction with respect to (% weight of succinimide). DSC was used to analyze the (melting temperature) T m and (crystallization temperature) T c values of functionalized LLDPE. Free radical mechanism explained the formation of nitroxide radical during the melt functionalization of N-hydroxy succinimide (NHS) with LLDPE in the presence of dicumyl peroxide.

Polystyrene (PS)-c-methacryloxypropyl trimethoxy silane (MPTMS) copolymer/zirconia (ZrO 2 ) nanohybrid materials were successfully prepared by the combination of solvothermal and in situ synthesis methods, in which the comonomer was used as chemical bonding agent between the nanoparticles and the matrix, and acetylacetone (AcAc) was used as a size control agent of ZrO 2 in the PS matrix. Then, a new transparency film with a relatively high refractive index (1.72) was successfully obtained, in which ZrO 2 could be dispersed well in the PS-MPTMS matrix. Field emission scanning electron microscopy images indicated that AcAc was helpful in the dispersion of the nanoparticles, and smaller ZrO 2 particles with no aggregation were obtained in the PS-MPTMS matrix. The structure and thermal properties of the hybrid films were investigated by Fourier transform infrared spectroscopy and thermogravimetric analysis, and the surface properties were also examined.
