Abstract

The invention relates to polymerisable compositions obtained as follows: a) reaction of A) between 0.5 and 5 parts by weight of at least one silicon compound of formula (I): SimR1nR2oOrXs with B) between 0.01 and 2.0 parts by weight of water C) between 0 and 4.0 parts by weight of at least one acid; and b) subsequent addition of D) between 0.5 and 5 parts by weight of at least one (meth)acrylate of formula (II), E) between 98.99 and 55 parts by weight of at least one polymerisable, ethylenically unsaturated monomer, different from D) and F) between 0 and 30 parts by weight of at least one polymer and/or copolymer, which is obtained by the polymerisation or copolymerisation of at least one ethylenically unsaturated monomer E). The invention also relates to polymers and laminate glass obtained from the composition and to a method for producing laminate glass.
