Silicones which contain lateral peripheral vinyl ether groups crosslinkable by cationic photoinitiators and their application for coatings and antiadhesive products for paper

摘要

The invention relates to copolymers of siloxanes with the formula: (Ra)3SiO(V)v-(W)w-(Y)y-(Z)z-Si(Ra)3 where V = -SiRaRbO-; W = -SiR'a(Rc-Rd-OCH=CH2)O-; Y = -SiRaRgO-; Z = -RaRgSiCnH2nR'fCnH2nSiRaRgO- where n = 2, 3 or 4; v, y, z = 0 or an integer, w NOTEQUAL 0 with v + y + z NOTEQUAL 0; Ra = alkyl or phenyl; Rb = Ra; R'a = Ra or alkoxy; Rc = alkylene, for example: Rd = -OCONHReNHCO-, -NH-COOC2H4-or -NHCOOC3H6-; Re = divalent hydrocarbon radicals; Rg, Rf and R'f are fluorinated or perfluorinated radicals. Use for the preparation of antiadhesive coatings, for example, on paper.
