Extensional-flow-induced Crystallization of Polypropylene
Extensional-flow-induced Crystallization Polypropylene
2014/10/23
A filament stretching extensional rheometer with a custom-built oven was used to investigate the effect of uniaxial flow on the crystallization of polypropylene. Prior to stretching, samples were heat...
