If PP and PE are the dominant component of a TPO blend then the rubber fraction will be dispersed into a continuous matrix of "crystalline" polypropylene. If the fraction of rubber is greater than 40% phase inversion may be possible when the blend cools, resulting in an amorphous continuous phase, and a crystalline dispersed phase.
Randomly functionalized polyolefins have differing types, location, and amount of functionality on the polyolefin backbone. Randomly functionalized polyolefins can be synthesized through many familiar combination of polymerization techniques including: post-functionalization, ROMP/hydrogenation, ADMET/hydrogenation, radical polymerization, and catalytic copolymerization.
The Barton–Kellogg reaction is a coupling reaction between a diazo compound and a thioketone, giving an alkene by way of an episulfide intermediate. The Barton–Kellogg reaction is also known as Barton–Kellogg olefination and Barton olefin synthesis.

Grubbs catalysts are of interest for olefin metathesis. [ 25 ] [ 26 ] It is mainly applied to fine chemical synthesis. Large-scale commercial applications of olefin metathesis almost always employ heterogeneous catalysts or ill-defined systems based on ruthenium trichloride.
When the α-silyl carbanion contains only alkyl, hydrogen, or electron-donating substituents, the stereochemical outcome of the Peterson olefination can be controlled, [7] because at low temperature the elimination is slow and the intermediate β-hydroxysilane can be isolated.

He then extended his experimentation to internal olefins and cyclic olefins, substances that are not normally polymerized by could serve as olefin metathesis substrates. [7] Many researchers followed on Eleuterio's initial discovery, [ 8 ] culminating in the 2005 Nobel Prize to Chauvin, Grubbs, and Schrock for the development of olefin ...
