Abstract:
Fluorocarbon- and urethane-(meth)acryl-containing additives and hardcoats. The hardcoats are particularly useful as a surface layer on an optical device.
Abstract:
Described herein is a melt-processible polymer composition comprising: a non-fluorinated melt-processible polymer; and a fluoropolymer derived from the polymerization of a monomer and a sulfinate-containing molecule, wherein the sulfinate-containing molecule is selected from the group consisting of: (a) CX1X3═CX2—(R)p—CZ1Z2—SO2M Formula (I) (b) Formula (II); and (c) combinations thereof, wherein X1, X2, and X3 are each independently selected from H, F, Cl, a C1 to C4 alkyl group, and a C1 to C4 fluorinated alkyl group; R is a linking group; Z1 and Z2 are independently selected from F, CF3, and a perfluoroalkyl group; R1 and R2 are end-groups; p is 0 or 1; m is at least 2; and M is a cation.
Abstract:
A hardcoat composition comprises (a) an epoxy silane compound, (b) a reactive silicone additive and (c) photo-acid generator. The reactive silicone additive has one of the following general structures:formula (I) or X—SiR1R2—(O—SiR1R2)n-X (Formula 2) wherein: R1, R2, and R3 are independently a C1-C6 alkyl group or aromatic group with or without substitution; X is a curable group selected from —OH, —OR, —OC(0)R, —OSiŶY3, —CHzCHrL-SiYVY3, and —C(O)(R)3, wherein: L is a divalent linkage group; Y1, Y2, and Y3 are independently selected from a C1-C6 alkyl group, and a curable group selected from —OH, —OC(O)R, and —OR, with the proviso that at least one of Y1, Y2, and Y3 is a curable group; R is a C1-C4 alkyl group; and n is at least 2 and m is at least 1, provided that the weight average molecular weight (Mw) of the reactive silicone additive is no more than 4200.
