Abstract: Provided is an adhesive composition suitable for producing a laminate. The composition contains specified amounts of (a) polyisobutyl methacrylate, isobutyl methacrylate or a mixture thereof, (b) butyl acrylate, (c) polybutyl acrylate, (d) a (meth)acrylate compound and (e) a silicon compound. These components may be in polymerizable form, in polymerized form or in a combination of polymerizable form and polymerized form. The amounts of components (a) to (e) total 100 wt. % and the amount of (b) and (c) represents 30 to 90 wt. %, based on the sum total of components (a) to (e). The composition may optionally further contain from 0.1 to 6 wt. %, based on the total weight of the adhesive composition, of additives different from components (a) to (e) described above.

Abstract: The invention relates to a new adhesive composition and to sheets produced from it, for producing laminates, more particularly for bonding plastic with glass components, to a method for producing such laminates, and to the laminates produced accordingly.

Abstract: The invention relates to novel poly(meth)acrylates for producing moulding compositions. In particular, the invention relates to novel methacrylates having ester groups which, in the cleavage process, liberate at most only a very small amount of components which are not re-copolymerizable. Copolymerization of monomers of this type in the production of the novel poly(meth)acrylates for moulding compositions brings about only minimal alteration of the heat resistance of these materials or may indeed improve the same.

Abstract: The invention relates to a method for coloring thermoplastic molding compounds, preferably a polymethyl(meth)acrylate molding compound, using novel aqueous colorant preparations. The invention further relates to a novel water-based colorant preparation.

Abstract: The invention provides a process for preparing 1-alkoxy-2-methyl-1-oxopropan-2-yl(meth)acrylate, e.g. 1-methoxy-2-methyl-1-oxopropan-2-yl(meth)acrylate, by transesterifying alkyl ?-hydroxyisobutyrates. Copolymerization of such monomers in the preparation of poly(meth)acrylate-based moulding materials improves the heat distortion resistance thereof.
