VISCOSITY IMPROVERS FOR COPOLYMER POLYETHYLENE - POLYPROPYLENE SOLUTIONS
Journal Title: Journal of Science And Arts - Year 2013, Vol 23, Issue 2
Abstract
In this article we presented viscosity indices for poly (ethylene-copropylene) copolymer solutions in rapeseed oil using three methods. Viscosity indices are calculated from the measured viscosity at 40 and 100 ºC according to ASTM D 2270, using program VI and graphical method from ASTM D 341. The viscosity-temperature coefficients for poly (ethylene-co-propylene) copolymer solutions in rapeseed oil were calculated from the measured viscosity at 40 and 100 ºC
