| 摘要 |
<p>This invention relates to polymeric compositions derived by the polycondensation of heteroatom containing perfluoroalkyl terminated neopentyl glycols, and diamino, dihydroxy, or dimercapto-polysiloxyanes and optionally other dosis, dimercaptans or diamines with organic diisocyanates; and blends of said polycondensation polymers with oxime-blocked organic polyisocyanates. These compositions and blends are useful as coatings on glass, wood, paper, leather and especially textiles.</p> |
