Abstract

Polymer blends based on polyacetal (POM) and acrylomtrile butadiene rubber (NBR) were prepared by melt blending technique.The mixing parameters such as temperature, time and speed of mixing were varied to obtain a wide range of properties. The mixing parameters were optimized by evaluating the mechanical properties of the blend over a wide range of mixing conditions. The morphology of the blend indicated a two-phase structure. This study describes an attempt to improve the tensile strength of POM/NBR blends by means of compatibilization and DYNAMIC VULCANIZATION. A commercial COMPATIBILIZER, MALEIC ANHYDRIDE (MA), has been used to control the phase morphology of the blend system. Dicumyl peroxide is used to dynamically vulcanize the NBR elastomer in the blend. The tensile strength of the compatibilized systems showed improvement. DYNAMIC VULCANIZATION raises elastic recovery and tensile modulus of the blends, but the elongation at break decreases.
