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