Natural oil metathesis compositions

Abstract

A metathesized natural oil composition comprising a blend of (i) a high molecular weight metathesized natural oil, and (ii) at least 10% of metathesized natural oil back blended with the high molecular weight metathesized natural oil. The blend has a number average molecular weight in the range from about 300 g/mol to about 76,000 g/mol, a weight average molecular weight in the range from about 300 g/mol to about 81,000 g/mol, a z-average molecular weight in the range from about 300 g/mol to about 87,000 g/mol, and a polydispersity index of about 0.5 to about 1.5. The metathesized natural oil composition is metathesized at least once.
