    摘要: The present invention comprises a novel formulation for marking trafficways, for example roads, which when compared with the prior art have improved mechanical properties and improved heat resistance during curing. The invention also relates to improved reactive resins for other applications than roadmarkings. The present invention in particular relates to reactive resins which comprise core-shell particles.

    摘要: The invention relates to a process for production of methacrylic acid, to a process for production of methyl methacrylate comprising the process steps a) providing a feed composition comprising at least one C 4 feed compound selected from isobutylene and tertiary butanol; b) providing methanol; c) subjecting the at least one C4 feed compound and the methanol to a first catalytic reaction zone to obtain a reaction phase comprising methyl tertiary butyl ether; d) separating at least a first part of methanol from the reaction phase to obtain a first methanol phase and a reaction phase depleted in methanol; e) subjecting at least one of the reaction phase and the reaction phase depleted in methanol to a second catalytic reaction zone to obtain a splitting phase comprising isobutylene and methanol; f) optionally separating at least a first part of isobutylene from the second reaction phase to obtain a first isobutylene phase and a splitting phase depleted in isobutylene; g) optionally subjecting the first isobutylene phase to a first purification zone; h) subjecting the optionally purified first isobutylene phase to a third catalytic reaction zone to obtain an oxidation phase comprising at least one C 4 oxidation product selected from methacrolein and methacrylic acid; i) optionally subjecting the oxidation phase to a second purification zone; j) subjecting the optionally purified oxidation phase to a fourth catalytic reaction zone to obtain an esterification phase comprising methyl methacrylate; k) optionally subjecting the esterification phase to a third purification zone, to an apparatus for production of methacrylic acid, to an apparatus for production of methyl methacrylate, to a process carried out in the apparatus, to methacrylic acid, to methyl methacrylate, to methacrylate esters, to a process for preparation of a polymer comprising at least one methacrylic acid, methyl methacrylate and/or methacrylate ester monomer unit, to a polymer comprising at least one methacrylic acid, methyl methacrylate and/or methacrylate ester monomer, to a process for preparation of a composition, to a composition, to chemical products, and to the use of at least one of methacrylic acid, methyl methacrylate, methacrylate ester, a polymer and/or a composition in chemical products.
