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.

Adhesive for producing composite bodies, a plastic glass composite or composite glass for architecture and construction

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.

Homopolymers and copolymers of hydroxyisobutyric acid (ester) (meth) acrylates

The invention relates to a macroporous plastics bead material with an average particle diameter from 10 to 1000 &#x3bc;m, containing a copolymer of a) 5-60 wt. % vinylically polymerizable monomers with a water solubility of at least 1% at 20&#xb0; C., b) 1-40 wt. % vinylically polymerizable monomers with an additional functional group, which can enter into covalent bonds with the nucleophilic groups of the ligands in a polymer-like reaction, c) 10-40 wt. % hydrophilic, crosslinking radical-polymerizable monomers with two or more ethylenically unsaturated polymerizable groups and d) 10-60 wt. % vinylically polymerizable monomers with a water solubility of at most 1% at 20&#xb0; C. are contained, as a rule with the monomers a) to d) adding up to 100%.

Macroporous material in the form of plastic pearls

The invention relates to a process for synthesis, by inverse bead polymerization of a monomer phase, of a bead-like, cross-linked, hydrophilic copolymer which has binding activity toward ligands containing nucleophilic groups. The invention relates to support polymer materials with high binding capacity for penicillin acylase and low swelling factor, as well as to use of the same.
