These 10 facts about space will blow your mind. Olefin, also known as polypropylene or polyethylene, is a long-chain polymer synthetic fiber. It is created when ethylene and/or propylene gases are polymerized under very specific conditions. The fiber was first manufactured in the late 1950s, and has myriad applications in manufacturing, household products, and clothing.
Olefin metathesis is one of the very few fundamentally novel organic reactions discovered in the last 40 years. Among others, it opens up new industrial routes to important petrochemicals, polymers, oleochemicals and specialty chemicals.
