    Abstract: A process for the final preparation of polymer dispersions, in which the dispersion is circulated from a vessel (7) fitted with a stirrer (6) through a line (3) with a mixer (2) by means of a pump (4) in line (3), and treated with solution(s) or dispersion(s) of finishing agent(s) (I) which is/are injected from storage tank(s) (5) via a feed line (9) before the dispersion enters the mixer (2).

    Abstract: The invention concerns a process for preparing aqueous polymer dispersions by the emulsion-polymerization of olefinically unsaturated compounds. The invention is characterized in that the water-soluble initiator used is added at least partially in the form of an aqueous initiator solution which comprises a surfactant and the initiator or, in the case of reduction-oxidation (redox) initiator system, at least one initiator component (emulsified initiator solution).

    Abstract: The invention relates to radiation-reactive mixtures of certain precursors and carbonyl compounds which contain aromatic radicals and, in the UV-excited state, are capable of hydrogen abstraction, which mixtures experience a solubility differentiation on irradiation with actinic light and are suitable for the preparation of polyimides, polyisoindoloquinazolinediones, polyoxazinediones, polyquinazolinediones or polyquinazolones. … They are suitable for the production of insulating layers and printed circuit boards.

    Abstract: Aqueous synthetic resin formulations essentially contain A) from 3 to 75% by weight of one or more synthetic resins which are composed of a) from 50 to 99.9% by weight of one or more unsaturated carboxylic or vinyl esters, b) from 0.1 to 12% by weight of one or more alpha , beta -monoethylenically unsaturated monobasic or dibasic acids or their ahydrides, c) from 0 to 10% by weight of one or more monoethylenically unsaturated acetophenone or benzophenone derivatives, d) from 0 to 35% by weight of one or more other copolymerizable monoethylenically unsaturated monomers, in polymerized form, B) one or more metal cations having a charge of from 2 to 4, in water-soluble form, C) from 0 to 10% by weight, based on the synthetic resin A, or benezophenones or acetophenones which are not monoethylenically unsaturated, D) effective amounts of emulsifiers or protective colloids or a mixture of these active ingredients, E) not less than 5% by weight of water and F) from 0 to 85% by weight of finely divided fillers, and the total amount of the cations B is such that it is capable of neutralizing from 0.2 to 6 times the amount, corresponding to the amount of acid functions incorporated in the form of the monomers b in the synthetic resin A, of their conjugated bases. These synthetic resin formulations are suitable for coating, adhesive bonding, sealing or impregnating.
