Peroxidic perfluoropolyethers (PFPEs) are industrial intermediates used by Solvay Solexis for the preparation of different classes of (per)fluoropolyethers (Fomblin®, Galden®, Solvera®, Fluorolink®). The chemistry of these peroxidic compounds has been recently exploited for the synthesis of novel PFPE block copolymers. In the present work we report the synthesis, the structural and physical–chemical
过氧化全氟聚醚聚醚(PFPE)为不同的类(全)氟聚醚的聚醚(Fomblin的制备中使用由Solvay Solexis公司工业中间体®,热传导液®,Solvera ®,的Fluorolink ®)。这些过氧化物的化学性质最近已被用于合成新型PFPE嵌段共聚物。在本工作中,我们报告了通过过氧化PFPE与2,2,4-三氟-5-三氟甲氧基-1,3-二恶唑(一种环状均聚全氟烯烃)的反应获得的嵌段共聚物的合成,结构和物理化学特性。这些嵌段共聚物结合了PFPE最具吸引力的性能,例如出色的润滑性,高的热稳定性和光学透明性,以及与全氟二氧烯烃嵌段相关的新的特定性能。
