Abstract: The invention relates to a dual component system with a controllable pot life. Said system can be hardened by a redox initiator system and comprises an emulsion polymer or a plurality of emulsion polymers and an ethylenically unsaturated monomer or a monomer mixture made from ethylenically unsaturated monomers. The emulsion polymer as well as the monomer or the monomer mixture can contain one of the components of a redox initiator system. Pot life is controlled by absorption of the redox initiator system on the polymer (A and B).

Abstract: Coatings and binders for pharmaceutical forms containing a copolymerizate, wherein the copolymerizate is made up of:A) 10 to 25 wt % methacrylic acid;B) 40 to 70 wt % methyl acrylate; andC) 20 to 40 wt % methyl methacrylate; based on the total weight of the copolymerizate.

Abstract: The invention relates to compatible PM polymer blends with polyesters as mix components, which compriseA) 0.1 to 99.9 wt % of a P1 polyester synthesized from units of formula I ##STR1## where R stands for a group --(CH.sub.2).sub.m -- or for a group ##STR2## and where m stands for a number from 2 to 6, andB) 99.9 to 0.1 wt % of a P2 polyester synthesized to 20-100 wt % from halogen-free monomers of formula II ##STR3## where R.sub.1 stands for hydrogen or methylR.sub.2 stands for a spacing group having 1-6 monomers,R.sub.3 stands for an alkyl group, alkoxy group or aminoalkyl- or dialkyl group having 1 to 6 carbon atoms andq stands for zero or one andz stands for zero, one or two.

Abstract: Multi-layer plastic elements containing a polycarbonate core, with a polymethacrylate layer containing a UV absorber, and modified to be impact-resistant, applied to the core, where the polymethacrylate plastic layer is composed of methacrylate copolymers, which form compatible mixtures with polycarbonate, especially the polycarbonate of bisphenol A, exhibit good adhesion between the polycarbonate and the polymethacrylate. The methacrylate copolymers are methyl methacrylate copolymers with (meth)acrylic monomers which contain carbocyclic substituents in the ester group. The protective layer containing UV absorber is applied to the polycarbonate plastic in thickness from 1 to 500 .mu.m by coextrusion or by lacquering.
