    Abstract: PROBLEM TO BE SOLVED: To prepare a homogeneous mixture continuously from first and second fluid bodies or solid components by using a tubular reactor equipped with one or more flow rate restricting members opened automatically when a flow rate is increased to enlarge the cross-sectional area of the reactor. SOLUTION: From a storage tank 1 having an agitator 2, a first fluid mixing component such as a polymer dispersion is supplied to a reactor 5, equipped with shell rings arranged continuously, flow restricting members, and a nozzle ring having three groove holes twisted mutually at 60 deg., by a pump 4 through a conduit 3. To the reactor 5, a second mixing component such as a mixing agent is distributed/supplied over the whole length of the reactor by the pump 4 from an agitation storage tank 7 through a conduit 8. Local high density is avoided here, and the mixture of the first and second components with improved mixing quality is prepared. The obtained mixture is supplied to a second storage tank 6 or circulated/returned to the tank 1.

    Abstract: PROBLEM TO BE SOLVED: To provide a satisfactory process order even when an order of manufacturing plan is collapsed. SOLUTION: This manufacturing control method is executed according to the manufacturing plan and in the manufacturing control method of separable chemical processes to be used for manufacturing plural generated products A, B, C at a plurality of stages 1, 2, 3, a measured value based on an operation parameter at least one stage of the stages 1, 2, 3 is recorded, monitored, a signal is generated when the measured value exceeds a limit value, the manufacturing plan is calculated again, based on the signal and the processes, are executed, based on a new manufacturing plan of the stages 1, 2, 3.

    Abstract: PROBLEM TO BE SOLVED: To provide a blending method of a polymer dispersion capable of attaining a sufficient mixing degree of a blending material and the polymer dispersion and capable of executing with a relatively low expense for a device. SOLUTION: The polymer dispersion is circulated with a pump 4 arranged at a conduit 3 from a vessel 7 provided with an agitator 6 through a conduit 3 provided with a mixing device 2, and at least one soln. or dispersion of at least one blending material is measured and introduced into the circulating polymer from a storage vessel 5 through a feed pipe 9 before the entering of the circulating polymer dispersion to the mixing device 2. Thus, the generation of coagulated lump is remarkably reduced.

    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.

    Abstract: The UV-curable compositions are based on a binder preparation comprising (1) from 99.0 to 20% by weight of a copolymer, (2) from 1.0 to 80% by weight of monoolefinically unsaturated compounds and (3) from 0.0 to 20% by weight of olefinically polyunsaturated compounds and are characterised in that the copolymer (1) is obtainable by subjecting a mixture of (A) from 80 to 99.9% by weight of olefinically unsaturated monomers, (B) from 0 to 10% by weight of a copolymerisable olefinically unsaturated photoinitiator, and (C) from 0 to 10% by weight of a polymerisation-regulating photoinitiator to free-radical polymerisation, where the sum of (B) and (C) is at least 0.1% by weight and the stated percentages by weight are based on the sum of the weights of (A) + (B) + (C).

    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.
