Patent ID: 7968193

Claim:
A polymerizable composition prepared by: a) mixing and reacting in a medium A) from 0.5 to 5 parts by weight of at least one silicon compound of the formula (I): Si m R 1 n R 2 o O r X s (I) where each R 1 , independently of the others, is an alkenyl or cycloalkenyl radical having from 2 to 12 carbon atoms and optionally having one or more ester groups, each R 2 , independently of the others, is an alkyl or cycloalkyl radical having from 1 to 12 carbon atoms, each X, independently of the others, is a halogen atom or an alkoxy group having from 1 to 6 carbon atoms, m is a whole number greater than or equal to 1, n is a whole number from 1 to 2*m+1, o is a whole number from 0 to 2*m, r is a whole number from 0 to m−1, s is a whole number from 1 to 2*m+1, and where m, n, o, and s comply with the relationship (1): n+o+s=2*m+2 (1) with B) from 0.01 to 2.0 parts by weight of water, and C) from 0.01 to 4.0 parts by weight of at least one acid; thereby hydrolyzing the alkoxy groups, wherein the hydrolysis is carried out until a water phase initially present has disappeared during the reacting a) and a homogeneous single phase of the hydrolyzed mixture is obtained, and b) then adding to the homogeneous phase of a) D) from 0.5 to 5 parts by weight of at least one (meth)acrylate of the formula (II) where R 3 is a hydrogen atom or a methyl group, and R 4 is an aliphatic or cycloaliphatic radical having from 1 to 20 carbon atoms and having at least one hydroxy, thiol, primary amino, secondary amino, and/or one epoxy group, E) from 98.99 to 55 parts by weight of at least one polymerizable ethylenically unsaturated monomer other than D), F) from 0 to 30 parts by weight of at least one polymer and/or copolymer which is obtainable via polymerization or, respectively, copolymerization of at least one ethylenically unsaturated monomer E).
