TRIAZOLE-CONTAINING FLUOROCARBON-GRAFTED POLYSILOXANES

摘要

A polymer for imparting repellency and stain resistance to substrates is disclosed of Formula (1): (W)_a(R²)_b-Si(R¹)₂-O-[Si(R¹)₂-O]_n-[Si(W)_c(R¹)_d(R²)_e-O]_m-Si(R¹)₂-(W)_f(R²)_g wherein: a, b, c, d, e, f and g are each independently 0 or 1, provided that (a + b) is 1, (f + g) is 1, and (c + d + e) is 2, each R¹ is divalently a C₁ to C₈ alkyl, each R² is independently H or C₁ to C₈ alkyl, optionally containing oxygen, nitrogen, or sulfur, or a combination thereof, n = 0 to 500, m = 1 to 100, each W is independently (R_f-X-A-X)_p-Y wherein: R_f is a straight or branched perfluoroalkyl group having from about 2 to about 20 carbon atoms, or a mixture thereof, which is optionally interrupted by at least one oxygen atom, each X is independently an organic divalent linking group having from about 1 to about 20 carbon atoms, optionally containing oxygen, nitrogen, or sulfur, or a combination thereof, A is a 1, 2, 3-triazole, p = 0 to 2, and Y is O, OR, N, NR or N(R)₂ wherein R is H or C₁ to C₂₀ alkyl, optionally containing oxygen, nitrogen, or sulfur, or a combination thereof.
