Effect of ricinol-2-oxazoline methylmaleate on the structure and properties
of polyamide 6 and low density polyethylene blends
Polimery 2004, No 9, 623
Effect of PE-LD grafting with ricinol-2-oxazoline methylmaleate (MRO) on phase structure as well as thermal and mechanical properties of polyamide 6 and low-density polyethylene blends (PA 6/PE-LD-g-MRO), differing in composition, obtained in reactive extrusion process, has been studied. This effect was studied using the following methods: infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and dynamic mechanical/thermal analysis (DMTA). The blends show heterogenic structure which, as a result of chemical reactions going during the extrusion, stabilizes at microphase level. It advantageously influences mechanical properties. Results of investigations show the compatibilizing effect of MRO.
