Preparation Of Fluorinated Isotactic Polypropylene By Free Radical Reaction Combining Fluorinated Reagent And Bpo

The incorporation of fluorine into polyolefin can dramatically improve its own mechanical properties and compatibility with other polymers, which has revolutionized the development of polyolefin industry. However, there were no fluorinated isotactic polypropylene (iPP) on the market which remains a formidable challenge. Here, a novel approach is presented that fluorinated iPP was prepared by free radical reaction using N-fluorobenzenesulfonimide (NFSI) as fluorine transfer reagent and benzoyl peroxide (BPO) as initiator in solution reaction. By conducting the tests of water contact angle (CA), DSC and TGA, the results indicated that the surface property and the thermal stability of fluorinated iPP (F-iPP) were greatly improved. In this contribution, a direct and economical route to fluorinate polyolefin was provided.
