    摘要： The invention relates to a polymer of core-shell structure containing a core having at least one elastomeric polymer, with a glass transition temperature of less than 25° C., and a shell having at least one polymer, with a glass transition temperature of greater than 25° C., where at least one of the polymers includes (meth)acrylic acid ester monomers containing organic carbon derived from biomass. The present invention also relates to a process for preparing the core-shell polymers and to their use as impact additives, and to a composition containing them.

    摘要： The invention relates to photosensitive compositions, which can be developed positively. Traditional compositions have either inadequate photosensitivity or they are not appropriate for use on the copper surfaces, for example of circuit boards, since the exposed coating sections of the composition cannot be completely removed during developing, which results in problems in subsequent plating or etching. In the photosensitive compositions according to the invention, these disadvantages cannot be observed. Various compositions are described, which contain photo acid generators and a polymer resin with side groups, which can split acid, said polymer resin being formed by polymerizing at least three different acrylate- or methacrylate-monomers.

    摘要： The present invention relates to hybrid impact modifiers prepared by: either spray drying, coagulation, freeze coagulation or other known recovery methods of a mixture of a latex or slurry of standard impact modifiers and a slurry of a mineral filler, either simultaneous drying (by spray-drying, coagulation other known recovery possible methods) of (i) a latex or slurry of standard impact modifiers and of (ii) a slurry of a mineral filler, further to the coagulation or freeze coagulation, if any, there is a filtration and drying step to recover these hybrid impact modifiers as a powder. The host polymers to be impact modified, can be any thermoplastic. Advantageously it can be polyvinyl chloride (PVC), polyamide (PA), polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC), thermoplastic polyesters such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycyclohexanedimethanol terephthalate, and polyolefins such as polyethylene (PE), polypropylene (PP), and any other matrix polymer which can be improved by an impact modifier.The present invention also relates to the use of said hybrid impact modifiers in thermoplastic polymers.The present invention also relates to a thermoplastic polymer containing said hybrid impact modifiers.The present invention also relates to hybrid impact modifiers having improved powder properties (flowability, lumping/caking resistance, segregation between the organic and the mineral parts).The present invention also relates to a thermoplastic polymer containing said hybrid impact modifiers with better dispersion homogeneities.

    摘要： The present invention is directed to a process for improving the dispersibility and the filterability of scleroglucan powders, in which a surfactant is incorporated in the coagulated polymer. The powder obtained according to the process has a dispersibility and a filterability after drying of the coagulum which are greatly superior to those of a powder treated after drying with the same quantity of surfactant or of a powder in solution treated with this same quantity of surfactant. The present invention is also directed to methods for preventing the sudden rush of well water into the strata of petroleum fields, to methods for modifying the injection profile, and to methods for improved hydrocarbon recovery from petroleum fields.
