Olefin fibre is a fibre used in activewear, linings, and warm clothing.34. Most theories assumed copper does not play a role in the olefin oxidation mechanisms. 35. These are versatile oxidising agents and may be used for the epoxidation of olefins . 36. This approach result in a distribution or full range of alpha-olefins . 37. There are two types of alpha-olefins , linear ( or normal ). 38. The process also makes a C4-C20 + distribution of alpha-olefins . 39. Excess ethylene and olefin diluent are flashed off. 40. Another significant application for C 16-C 18 olefins is in paper sizing.
