Abstract: The invention relates to radiation-sensitive 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: Nonaqueous polymer dispersions are obtainable by polymerization of esters (A) of acrylic acid and/or methacrylic acid and/or ethylacrylic acid with C1-C20-alcohols in an organic solvent or a mixture of organic solvents in which the polymers formed are insoluble, and in the presence of copolymers (B) having a molecular weight of from 500 to 20,000 and obtainable by bulk or solution polymerization of monoolefinically unsaturated monomers at from 180 DEG to 400 DEG C. and from 1 to 200 bar, and the said dispersions are used for the production of finishes, coating materials and adhesives.

Abstract: A tubular reactor (5) has one or more throttling restrictions, which automatically offer increased reaction cross section, as the volumetric flow rate increases. An Independent claim is included for the reactor/mixer carrying out the procedure. It includes a series of coincident openings rotated relatively and automatically, to achieve flow-dependent throttling action. Preferred Features: Volumetric flow rate of a first mixture component varies by a factor of \! 10, especially by \! 5. The viscosity difference between at least two mixture components prior to mixing exceeds 100 mPas, especially exceeding 1000 mPas. Volumetric flow rate ratio between first and further components is 1000 : 1, preferably 100 : 1; it especially lies in the range 5 : 1 to 1:1. The first liquid is a homogeneous or non-homogeneous liquid. It is especially a dispersion, preferably of a polymer. Further component(s) are homogeneous or non-homogenous fluids and/or solids and/or gases. The components react chemically.

Abstract: Synthetic resins are obtainable by chemically bonding one or more compounds of the general formula I (* CHEMICAL STRUCTURE *) (I) where R1 is -OH, -NH2, (* CHEMICAL STRUCTURE *) -NHR3 or (* CHEMICAL STRUCTURE *) R2 is -H, -CH3 or -C2H5, R3 is -CmH2m+1, where m is from 1 to 6, R4 is -H or -CH3 and n is from 1 to 12, via the oxygen or nitrogen atom of R1 to one or more polymers A which consist of a) from 50 to 100% by weight of one or more esters of acrylic or methacrylic acid with monohydric alcohols of 1 to 18 carbon atoms or a mixture of these esters (monomers a) and b) from 0 to 50% by weight of other copolymerizable monomers (monomers b) in polymerized form, in amounts such that the synthetic resin contains from 0.01 to 1 mole of double bonds per kg of polymer A. After exposure to ultraviolet light or to electrons, these synthetic resins are suitable as contact adhesives.
