Mechanical properties of Poly vinyl alcohol and Nitrocellulose blends.

Abstract

Mechanical properties of polyvinyl alcohol and nitrocellulose blends has been determined successfully via tensile strength, Young’s modulus, percentage elongation and impact strength. The blends of the respective polymers are in the ratio PVA:NC (90:10,80:20,60:40,50:0,40:60,10:90). There are good results from different blend ratios which include tensile strength PVA: NC 90:10 (16.98MPa) Young’s modulus 60:40 (0.71MPa). The highest percentage elongation was observed for 80:20 at 160.09%. The most elastic blend ration was found to be PVA: NC 10:90 with 0.17MPa while blend 90:10 was recorded with the highest impact strength value of  5.01kJm² .Some of the values recorded for blend 60:40 indicated the immiscibility of the polymers at this ratio.
