Silicone containing peripheral vinyl ether by cationic photoinitiators, which may be networked and used for coating and anti-adhesive treatment of 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.
