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.
An alpha-olefin (or α-olefin) is an alkene where the carbon-carbon double bond starts at the α-carbon atom, i.e. the double bond is between the #1 and #2 carbons in the molecule. Alpha-olefins such as 1-hexene may be used as co-monomers to give an alkyl branched polymer (see chemical structure below), although 1-decene is most commonly used ...
Thermoplastic polyolefin (TPO) single-ply roofing is the single most popular type of commercial low-slope roof covering as of 2016. [19] A TPO roof membrane consists of three layers: a TPO polymer base, a polyester reinforcement scrim middle layer, and a TPO polymer top ply, which are heat-fused at the factory.

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 Shell higher olefin process (SHOP) is a chemical process for the production of linear alpha olefins via ethylene oligomerization and olefin metathesis invented and exploited by Shell plc. [1] The olefin products are converted to fatty aldehydes and then to fatty alcohols , which are precursors to plasticizers and detergents .
