    Abstract: A process for preparing oligo ethylene glycol methyl ether borate involves feeding boric acid and oligo ethylene glycol monomethyl ether into a reactor, and reacting to obtain a raw product containing oligo ethylene glycol methyl ether borate, water, and unreacted boric acid and oligo ethylene glycol monomethyl ether. The raw product is fed to a reactive distillation device and boric acid is reacted with oligo ethylene glycmonomethyl ether for full conversion of boric acid. A distillate stream containing water is transferred from the top of the reactive distillation device to a condenser, and a condensed liquid stream is recycled to the top of the reactive distillation device. A bottom product stream containing oligo ethylene glycol methyl ether borate is withdrawn from the reactive distillation device. The bottom product stream is partially recycled to a reboiler. The resulting vapor stream is recycled to the bottom of the reactive distillation device.

    Abstract: The present invention relates to aqueous polymer dispersion of voided polymer particles and to a process for preparing such aqueous polymer dispersions. The present invention also relates to polymer particles, in particular powders of said polymer particles, which are obtained by drying a polymer dispersion. Further aspects of the present invention relate to the use of such voided polymer particles and the polymer dispersions as opacifiers and to paints containing such aqueous polymer dispersions. The voided polymer particles comprise: i) an alkali swellable polymer core of polymerized ethylenically unsaturated monomers M(i) comprising polymerized acid monomers M(i.ac) in an amount sufficient for allowing the polymer core to swell at a pH of at least pH 7.5; ii) an intermediate polymer layer of polymerized ethylenically unsaturated monomers M(ii); and iii) a polymer shell of polymerized ethylenically unsaturated monomers M(iii) having a theoretical glass transition temperature according to Fox of at least 60° C. where the monomers M(iii) comprise at least 10% b.w., based on the total weight of the monomers M(iii), of one or more monomers M(iii.a) whose homopolymers have a glass transition temperature of at least 50° C., where the monomer M(iii.a) is selected from the group consisting of C5-C20-cycloalkyl esters of acrylic acid, C5-C20-cycloalkyl esters of methacrylic acid, C5-C20-cycloalkylmethyl esters of acrylic acid, C5-C20-cycloalkylmethyl esters of methacrylic acid, where cycloalkyl in the aforementioned monomers is mono-, bi- or tricyclic and may be unsubstituted or carry 1, 2, 3 or 4 methyl groups; C3-C20-heterocycloalkyl esters of acrylic acid, C3-C20-heterocycloalkyl esters of methacrylic acid, C3-C20-heterocycloalkylmethyl esters of acrylic acid, C3-C20-heterocycloalkylmethyl esters of methacrylic acid, where heterocycloalkyl in the aforementioned monomers has a total of 5 to 16 ring-forming atoms, where 1, 2 or 3 non-adjacent ring-forming atoms are oxygen atoms while the remainder of the ring-forming atoms are carbon atoms, and where heterocycloalkyl is mono-, bi- or tricyclic and may be unsubstituted or carry 1, 2, 3 or 4 methyl groups; di-C1-C2-alkyl esters of itaconic acid; and combinations thereof.

    Abstract: An aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a) a polymer carrier prepared by heterophase radical polymerization of at least one ethylenically unsaturated monomer in the presence of b) an oil-soluble organic UV absorber selected from the class of p-aminobenzoic acid derivatives; salicylic acid derivatives; benzophenone derivatives; diphenyl acrylate derivatives; benzofuran derivatives; polymeric UV absorbers, comprising one or more organosilicon radicals; cinnamic acid derivatives; camphor derivatives; s-triazine derivatives; trianilino-striazine derivatives; menthyl anthranilates; and benzotriazole derivatives; wherein the weight ratio of the oil-soluble organic UV absorber (b) to polymer carrier (a) is greater than 50 parts UV absorber per 100 parts of carrier; and c) a surfactant selected from c1) a nonionic surfactant selected from c11) the condensation product of a C6 to C18 fatty alcohol or C6 to C18 fatty acid and a mono- or disaccharide; and c2) an anionic surfactant selected from c21) sulfosuccinates and sulfosuccinamates; c22) fatty alcoholates; and c23) mixtures of phosphoric acid esters and fatty alcohols having from 6 to 18, preferably from 8 to 10, carbon atoms. The aqueous polymer dispersions show unexpectedly high sunscreen effects and a positive skin feeling. They have excellent anti-pollen, anti-dust and anti-oxidant performances in sun screen compositions.

    Abstract: The present invention relates to information retrieval. In order to facilitate a search and identification of documents, there is provided a computer-implemented method for training a classifier model for data classification in response to a search query. The computer-implemented method comprises:



    a) obtaining a dataset that comprises a seed set of labeled data representing a training dataset;
    b) training the classifier model by using the training dataset to fit parameters of the classifier model;
    c) evaluating a quality of the classifier model using a test dataset that comprises unlabeled data from the obtained dataset to generate a classifier confidence score indicative of a probability of correctness of the classifier model working on the test dataset;
    d) determining a global risk value of misclassification and a reward value based on the classifier confidence score on the test dataset;
    e) iteratively updating the parameters of the classifier model and performing steps b) to d) until the global risk value falls within a predetermined risk limit value or an expected reward value is reached.
