Abstract
Official abstract text for this publication.
A metathesized natural oil composition comprising (i) a mixture olefins and/or esters, or (ii) a metathesized natural oil, is disclosed. The metathesized natural oil composition has a number average molecular weight in the range from about 100 g/mol to about 150,000 g/mol, a weight average molecular weight in the range from about 1,000 g/mol to about 100,000 g/mol, a z-average molecular weight in the range from about 5,000 g/mol to about 1,000,000 g/mol, and a polydispersity index of about 1 to about 20. The metathesized natural oil composition is metathesized at least once.
First claim
Opening claim text (preview).
We claim: 1. A metathesized natural oil composition comprising one or more metathesis oligomers, which are formed from the self-metathesis of natural oil glycerides, wherein the natural oil glycerides comprise metathesized natural oil glycerides, which are formed by the cross-metathesis of a natural oil glycerides with C 2 -C 6 low-molecular-weight olefins, and wherein the one or more metathesis oligomers have a weight average molecular weight in the range from 2,500 g/mol to 50,000 g/mol. 2. The metathesized natural oil composition of claim 1 , wherein the one or more metathesis oligomers have a weight average molecular weight in the range from 2,500 g/mol to 50,000 g/mol. 3. The metathesized natural oil composition of claim 1 , wherein the C 2 -C 6 low-molecular-weight olefins are selected from the group consisting of ethylene, propylene, 1-butene, 2-butene, and isobutene.
