Title:
【発明の名称】トリス-パーフルオロアルキル末端ネオペンチルアルコールおよびその誘導体
Document Type and Number:
Japanese Patent JP3024014
Kind Code:
B2
Abstract:
Tris-perfluoroalkyl terminated neopentyl alcohols of the formula (Rf-En-X-CH2)3CCH2OH prepared from halogenated neopentyl alcohols and thiols of the formula Rf-En-SH, amines of the formula Rf-En-NH-R, alcohols of the formula Rf-En-OH, perfluoro-acids or amides, are described. The alcohols react with isocyanates to prepare urethanes; with acids or derivatives, to prepare esters or carbonates; with epoxides to form ethers. Further, they may be converted to halide intermediates. The products all contain the residue of at least one Rf-neopentyl alcohol containing three perfluoroalkyl hetero groups. These compositions provide improved thermal stability and useful low surface energy oil and water repellent coatings, for textiles, glass, paper, leather and other substrates, and in spin finishes for textile fibers.
