Reaktionsschritte

A polyethylene terephthalate (PET) surface is coated with an 8% solids solution of MAPTAC/VP/SiAM 15/75/10 of Example 1a (1.5 mL of solution on a 5 cm*5 cm PET sheet, spin coating 1500 rpm, 15 s). The solvent used is a water/isopropyl alcohol mixture (70/30), in order to have a sufficient wetting of the PET sheet by the solution. After 7 days of drying in 75% RH atmosphere, a contact angle of 140° is measured with water.
